Associations Between Measures of Disability and Quality of Life at Three Months After Stroke.

Background: The modified Rankin Scale (mRS), which measures degree of disability in daily activities, is the most common outcome measure in stroke research. Quality of life (QoL), however, is impacted by factors other than disability. The goal of this study was to assess the correlation between functional dependence and a more patient-centered QoL measure, the European QoL visual analog scale (EQ VAS). Methods: We reviewed prehospital and hospital records from 11 acute care hospitals in Seattle, Washington (USA) from June 2000 to January 2003 for this cohort study. Patients with a final diagnosis of stroke were contacted three to four months after stroke, and mRS and EQ VAS were assessed. Good QoL was defined as EQ VAS ≥65. Results: Of 760 patients with stroke, 346 were available at three to four months. Most (296, 85.5%) had ischemic stroke. Overall, mRS and QoL were negatively correlated (Spearman's ρ -0.53, p < 0.001). Percentage of good QoL decreased as mRS increased from 0 to 5 (88%, 70%, 52%, 50%, 31%, 20%, respectively, p < 0.001). However, 36% (n = 62) of patients with dependent mRS (3-5, n = 174) reported good QoL, and 30% (n = 52) of patients with independent mRS (0-2, n = 172) reported poor QoL. In multivariable analysis, older age, male gender, and absence of dementia, were associated with good QoL despite dependent mRS; atrial fibrillation was associated with poor QoL despite independent mRS. Conclusions: QoL decreases with increasing mRS, but exceptions exist with good QoL despite high mRS. To provide patient-centered care, clinicians and researchers should avoid equating disability with QoL after stroke.

Fatigue, Toll-Like Receptor 4, and Pro-Inflammatory Cytokines in Adults With Subarachnoid Hemorrhage: A 6-Month Longitudinal Study.

BACKGROUND: Fatigue is prevalent in subarachnoid hemorrhage (SAH) survivors. Biological mechanisms underlying fatigue post-SAH are not clear. Inflammation may contribute to the development of fatigue. This study aimed to examine the associations between inflammatory markers and fatigue during the first 6 months post-SAH. Specific biomarkers examined included both early and concurrent expression of Toll-Like Receptor 4 (TLR4) messenger RNA (mRNA) and plasma concentrations of pro-inflammatory cytokines, Tumor Necrosis Factor-alpha (TNF-α), Interleukin (IL)1ß, and IL6. METHODS: We conducted a 6-month longitudinal study with a convenience sample of 43 SAH survivors. We collected blood samples on days 2, 3, and 7 and 2, 3, and 6 months post-SAH to assess biomarkers. Fatigue was assessed by the PROMIS Fatigue Scale at 2, 3, and 6 months. Linear mixed models were used to test the associations between early (days 2, 3, and 7) and concurrent (2, 3, and 6 months) TLR4 mRNA expression (TagMan gene expression assays) and TNF-α, IL1ß, and IL6 plasma concentrations (multiplex assays) and concurrent fatigue. RESULTS: 28% of SAH survivors experienced fatigue during the first 6 months post-SAH. Fatigue levels in SAH survivors were higher than those of the U.S. population and consistent during the 6 months. Experience of fatigue during the 6 months post-SAH was associated with higher IL1ß plasma concentrations on day 7 and IL1ß, IL6, and TNF-α plasma concentrations during the 6 months post-SAH. CONCLUSION: Inflammation appears to underlie the development of fatigue in SAH survivors.

Types of Stroke Among People Living With HIV in the United States.

BACKGROUND: Most studies of stroke in people living with HIV (PLWH) do not use verified stroke diagnoses, are small, and/or do not differentiate stroke types and subtypes. SETTING: CNICS, a U.S. multisite clinical cohort of PLWH in care. METHODS: We implemented a centralized adjudication stroke protocol to identify stroke type, subtype, and precipitating conditions identified as direct causes including infection and illicit drug use in a large diverse HIV cohort. RESULTS: Among 26,514 PLWH, there were 401 strokes, 75% of which were ischemic. Precipitating factors such as sepsis or same-day cocaine use were identified in 40% of ischemic strokes. Those with precipitating factors were younger, had more severe HIV disease, and fewer traditional stroke risk factors such as diabetes and hypertension. Ischemic stroke subtypes included cardioembolic (20%), large vessel atherosclerosis (13%), and small vessel (24%) ischemic strokes. Individuals with small vessel strokes were older, were more likely to have a higher current CD4 cell count than those with cardioembolic strokes and had the highest mean blood pressure of the ischemic stroke subtypes. CONCLUSION: Ischemic stroke, particularly small vessel and cardioembolic subtypes, were the most common strokes among PLWH. Traditional and HIV-related risk factors differed by stroke type/subtype. Precipitating factors including infections and drug use were common. These results suggest that there may be different biological phenomena occurring among PLWH and that understanding HIV-related and traditional risk factors and in particular precipitating factors for each type/subtype may be key to understanding, and therefore preventing, strokes among PLWH.

HIV Viremia and Risk of Stroke Among People Living with HIV Who Are Using Antiretroviral Therapy.

BACKGROUND: Rates of stroke are higher in people living with HIV compared with age-matched uninfected individuals. Causes of elevated stroke risk, including the role of viremia, are poorly defined. METHODS: Between 1 January 2006 and 31 December 2014, we identified incident strokes among people living with HIV on antiretroviral therapy at five sites across the United States. We considered three parameterizations of viral load (VL) including (1) baseline (most recent VL before study entry), (2) time-updated, and (3) cumulative VL (copy-days/mL of virus). We used Cox proportional hazards models to estimate hazard ratios (HRs) for stroke risk comparing the 75th percentile ("high VL") to the 25th percentile ("low VL") of baseline and time-updated VL. We used marginal structural Cox models, with most models adjusted for traditional stroke risk factors, to estimate HRs for stroke associated with cumulative VL. RESULTS: Among 15,974 people living with HIV, 139 experienced a stroke (113 ischemic; 18 hemorrhagic; eight were unknown type) over a median follow-up of 4.2 years. Median baseline VL was 38 copies/mL (interquartile interval: 24, 3,420). High baseline VL was associated with increased risk of both ischemic (HR: 1.3; 95% CI = 0.96-1.7) and hemorrhagic stroke (HR: 3.1; 95% CI = 1.6-5.9). In time-updated models, high VL was also associated with an increased risk of any stroke (HR: 1.8; 95% CI = 1.4-2.3). We observed no association between cumulative VL and stroke risk. CONCLUSIONS: Our findings are consistent with the hypothesis that elevated HIV VL may increase stroke risk, regardless of previous VL levels.

Brief Psychosocial Intervention to Address Poststroke Depression May Also Benefit Fatigue and Sleep-Wake Disturbance.

PURPOSE: This study aimed to determine if brief psychosocial/behavioral therapy directed to reduce poststroke depression would decrease fatigue and improve sleep-wake disturbance. DESIGN: A preplanned secondary data analysis from a completed clinical trial was conducted. METHODS: One hundred participants received usual care, in-person intervention, or telephone intervention. Depression, fatigue, and sleep-wake disturbance were measured at entry, 8 weeks, 21 weeks, and 12 months following the intervention. FINDINGS: Fatigue (within: p = .042, between: p = .394), sleep disturbance (within: p = .024, between: p = .102), and wake disturbance (within: p = .004, between: p = .508) decreased over the 12 months in the intervention groups, but not in the control group. This difference was clinically meaningful for wake disturbance and approached the clinically important difference for fatigue. CONCLUSIONS/CLINICAL RELEVANCE: Reduction in wake disturbance was consistent with clinically meaningful difference standards for patient-reported outcomes, warranting further research in larger samples.

Impact of Age on Plasma Inflammatory Biomarkers in the 6 Months Following Mild Traumatic Brain Injury.

OBJECTIVE: To compare plasma inflammatory biomarker concentrations to 6 months in young and older adults with and without mild traumatic brain injury (TBI). SETTING: Level 1 trauma center. PARTICIPANTS: Younger (21-54 years) and older (55+) adults diagnosed with mild TBI along with age-/sex-matched noninjured controls (n = 313). DESIGN: Prospective cohort study. MAIN MEASURES: Multiplex assays were used to quantify concentrations of selected plasma inflammatory markers at day 0, months 1 and 6. RESULTS: Persistent aging-related differences were found between control groups in concentrations of 4 cytokines up to 6 months. At day 0, interleukin-6 (IL-6), IL-8, and fractalkine were higher in the older TBI compared with older control as well as the younger TBI groups, while IL-10 was higher in older TBI compared with controls. At month 1, significantly higher concentrations of IL-8, fractalkine, and tumor necrosis factor-α (TNF-α) were seen. At 6 months postinjury, significantly higher concentrations of IL-6 and IL-8 were seen, while a lower concentration of IL-7 was found in older versus younger TBI groups. CONCLUSION: The neuroinflammatory signature that accompanies mild TBI in older adults differs from that of younger adults. The differences seen are notable for their roles in neutrophil attraction (IL-8), neuronal-microglial-immune cell interactions (fractalkine), and chronic inflammation (IL-6).

Self-efficacy is associated with better sleep quality and sleep efficiency in adults with subarachnoid hemorrhage.

Subarachnoid hemorrhage (SAH) survivors often experience sleep disturbances. Self-efficacy for managing chronic disease may impact sleep for SAH survivors; however, little is known about the relationship between self-efficacy and subjective and objective sleep measures. The purpose of this study was to examine the associations among self-efficacy and subjective (nighttime sleep quality and daytime sleepiness) and objective (total sleep time [TST], wake after sleep onset [WASO], and sleep efficiency [SE]) sleep measures in SAH survivors. A cross-sectional study with a convenience sample of 30 SAH survivors was conducted. Self-efficacy was assessed with the Self-Efficacy for Managing Chronic Disease scale. Nighttime sleep quality and daytime sleepiness were assessed with the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale, respectively. SAH survivors wore a wrist actigraph for 7 days to estimate TST, WASO, and SE. Analyses revealed that, within 3 months post-SAH, 73% of SAH survivors experienced poor sleep quality and 27% reported excessive daytime sleepiness. In addition, 41.4% of the participants slept on average either < 7 h or > 9 h. Self-efficacy was correlated with nighttime sleep quality (r = -0.394, p = .031) and SE (r = 0.412, p = .026), but not with daytime sleepiness (r = -0.257, p = .170), TST (r = 0.137, p = .447), or WASO (r = -0.223, p = .246). Sleep disturbances are prevalent in SAH survivors. Targeted interventions focused on self-efficacy and self-management behaviors in this population may improve sleep and lead to better health.

Stroke impact symptoms are associated with sleep-related impairment.

BACKGROUND: Sleep-related impairment is a common but under-appreciated complication after stroke and may impede stroke recovery. Yet little is known about factors associated with sleep-related impairment after stroke. OBJECTIVE: The purpose of this analysis was to examine the relationship between stroke impact symptoms and sleep-related impairment among stroke survivors. METHODS: We conducted a cross-sectional secondary analysis of a baseline (entry) data in a completed clinical trial with 100 community-dwelling stroke survivors recruited within 4 months after stroke. Sleep-related impairment and stroke impact domain symptoms after stroke were assessed with the Patient-Reported Outcomes Measurement Information System Sleep-Related Impairment scale and the Stroke Impact Scale, respectively. A multivariate regression was computed. RESULTS: Stroke impact domain-mood (B = -0.105, t = -3.263, p = .002) - and fatigue (B = 0.346, t = 3.997, p < .001) were associated with sleep-related impairment. CONCLUSIONS: Our findings suggest that ongoing stroke impact symptoms are closely related to sleep-related impairment. An intervention targeting both stroke impact symptoms and sleep-related impairment may be useful in improving neurologic recovery and quality of life in stroke survivors.

Impact of aging on the immune response to traumatic brain injury (AIm:TBI) study protocol.

BACKGROUND: Traumatic brain injury (TBI) in older adults leads to considerable morbidity and mortality. Outcomes among older adults with TBI are disparately worse than in younger adults. Differences in immunological response to injury may account for at least some of this disparity. Understanding how ageing differentially affects the immune response to TBI and how older age and these immunological changes affect the natural history of recovery following TBI are the goals of this study. DESIGN/METHODS: A prospective multiple cohort design is being used to assess the effects of ageing and TBI on immune makers and to test predictors of impairment and disability in older adults following mild TBI. Older adults (>55 years) with mild TBI are enrolled with three comparison groups: younger adults (21-54 years) with mild TBI, non-injured older adults (>55 years) and non-injured young adults (21-54 years). For the primary analysis, we will assess the association between immune markers and Glasgow Outcome Scale-Extended at 6 months, using logistic regression. Predictors of interest will be inflammatory biomarkers. Multivariate linear regression will be used to evaluate associations between biomarkers and other outcomes (symptoms, function and quality of life) at 3 and 6 months. Exploratory analyses will investigate the utility of biomarkers to predict outcome using receiver-operating characteristic curves. DISCUSSION: A better understanding of the recovery trajectory and biological rationale for disparate outcomes following TBI in older adults could allow for development of specific interventions aimed at reducing or eliminating symptoms. Such interventions could reduce impairment and healthcare costs.

Association Between Bilirubin, Atazanavir, and Cardiovascular Disease Events Among People Living With HIV Across the United States.

OBJECTIVE: Bilirubin is an antioxidant that may suppress lipid oxidation. Elevated bilirubin is associated with decreased cardiovascular events in HIV-uninfected populations. We examined these associations in people living with HIV (PLWH). METHODS: Potential myocardial infarctions (MIs) and strokes were centrally adjudicated. We examined MI types: type 1 MI (T1MI) from atherosclerotic plaque instability and type 2 MI (T2MI) in the setting of oxygen demand/supply mismatch such as sepsis. We used multivariable Cox regression analyses to determine associations between total bilirubin levels and outcomes adjusting for traditional and HIV-specific risk factors. To minimize confounding by hepatobiliary disease, we conducted analyses limited to bilirubin values <2.1 mg/dL; among those with fibrosis-4 values <3.25; and among everyone. We repeated analyses stratified by hepatitis C status and time-updated atazanavir use. RESULTS: Among 25,816 PLWH, there were 392 T1MI and 356 T2MI during follow-up. Adjusted hazard ratios for the association of higher bilirubin levels with T1MI were not significant. Higher bilirubin levels were associated with T2MI. By contrast, among PLWH on atazanavir, higher bilirubin levels were associated with fewer T2MI (hazard ratio 0.56:0.33-1.00). Higher bilirubin levels among those on atazanavir were associated with fewer T1MI combined with ischemic stroke. LIMITATIONS: Analyses were conducted with total rather than unconjugated bilirubin. CONCLUSIONS: Among PLWH, higher bilirubin levels were associated with T2MI among some subgroups. However, among those on atazanavir, there was a protective association between bilirubin and T2MI. These findings demonstrate different associations between outcomes and elevated bilirubin due to diverse causes and the importance of distinguishing MI types.

Chemical Sympathectomy, but not Adrenergic Blockade, Improves Stroke Outcome.

BACKGROUND: A robust adrenergic response following stroke impairs lymphocyte function, which may prevent the development of autoimmune responses to brain antigens. We tested whether inhibition of the sympathetic response after stroke would increase the propensity for developing autoimmune responses to brain antigens. METHODS: Male Lewis rats were treated with 6-hydroxydopamine (OHDA) prior to middle cerebral artery occlusion (MCAO), labetalol after MCAO, or appropriate controls. Behavior was assessed weekly and animals survived to 1 month at which time ELISPOT assays were done on lymphocytes from spleen and brain to determine the Th1 and Th17 responses to myelin basic protein (MBP), ovalbumin (OVA), and concanavalin A. A subset of animals was sacrificed 72 hours after MCAO for evaluation of infarct volume and lymphocyte responsiveness. Plasma C-reactive protein (CRP) was measured as a biomarker of systemic inflammation. RESULTS: Despite similar initial stroke severity and infarct volumes, 6-OHDA-treated animals lost less weight and experienced less hyperthermia after stroke. 6-OHDA-treated animals also had decreased CRP in circulation early after stroke and experienced better neurological outcomes at 1 month. The Th1 and Th17 responses to MBP did not differ among treatment groups at 1 month, but the Th1 response to OVA in spleen was more robust in labetalol and less robust in 6-OHDA-treated animals. CONCLUSIONS: Chemical sympathectomy with 6-OHDA, but not treatment with labetalol, decreased systemic markers of inflammation early after stroke and improved long-term outcome. An increase in Th1 and Th17 responses to MBP was not seen with inhibition of the sympathetic response.

Minority Patients are Less Likely to Undergo Withdrawal of Care After Spontaneous Intracerebral Hemorrhage.

BACKGROUND: Prior studies of patients in the intensive care unit have suggested racial/ethnic variation in end-of-life decision making. We sought to evaluate whether race/ethnicity modifies the implementation of comfort measures only status (CMOs) in patients with spontaneous, non-traumatic intracerebral hemorrhage (ICH). METHODS: We analyzed data from the Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study, a prospective cohort study specifically designed to enroll equal numbers of white, black, and Hispanic subjects. ICH patients aged ≥ 18 years were enrolled in ERICH at 42 hospitals in the USA from 2010 to 2015. Univariate and multivariate logistic regression analyses were implemented to evaluate the association between race/ethnicity and CMOs after adjustment for potential confounders. RESULTS: A total of 2705 ICH cases (912 black, 893 Hispanic, 900 white) were included in this study (mean age 62 [SD 14], female sex 1119 [41%]). CMOs patients comprised 276 (10%) of the entire cohort; of these, 64 (7%) were black, 79 (9%) Hispanic, and 133 (15%) white (univariate p < 0.001). In multivariate analysis, compared to whites, blacks were half as likely to be made CMOs (OR 0.50, 95% CI 0.34-0.75; p = 0.001), and no statistically significant difference was observed for Hispanics. All three racial/ethnic groups had similar mortality rates at discharge (whites 12%, blacks 9%, and Hispanics 10%; p = 0.108). Other factors independently associated with CMOs included age (p < 0.001), premorbid modified Rankin Scale (p < 0.001), dementia (p = 0.008), admission Glasgow Coma Scale (p = 0.009), hematoma volume (p < 0.001), intraventricular hematoma volume (p < 0.001), lobar (p = 0.032) and brainstem (p < 0.001) location and endotracheal intubation (p < 0.001). CONCLUSIONS: In ICH, black patients are less likely than white patients to have CMOs. However, in-hospital mortality is similar across all racial/ethnic groups. Further investigation is warranted to better understand the causes and implications of racial disparities in CMO decisions.

Endovascular Treatment of Acute Ischemic Stroke Under General Anesthesia: Predictors of Good Outcome.

BACKGROUND: The choice of anesthetic technique, general anesthesia (GA) versus Monitored Anesthesia Care, may impact the outcome of patients undergoing endovascular treatment of acute ischemic stroke (AIS). The aim of this study was to identify the factors associated with good discharge outcome in patients receiving GA for AIS. MATERIALS AND METHODS: Electronic medical records of patients above 18 years old who underwent endovascular treatment of AIS under GA at a Comprehensive Stroke Center from 2010 to 2014 were reviewed. Good outcome was defined as discharge modified Rankin Score 0 to 2 and poor outcome as modified Rankin Score 3 to 6; logistic regression analysis was performed to examine the association between the clinical characteristics and the outcome. RESULTS: In total, 88 patients (56 males), aged 63±15 years with median National Institute of Health Stroke Scale (NIHSS) score 16 (range, 4 to 38) were included. Nineteen (22%) patients had good outcome and 78 (88%) had systolic blood pressure below the guideline recommended 140 mm Hg under GA. After adjusting for age and NIHSS score, the independent predictors of good discharge outcomes were higher maximum end-tidal carbon dioxide (odds ratio [OR], 1.14; confidence interval [CI], 1.02-1.28; P=0.02) and extubation after endovascular treatment (OR, 26.31; CI, 4.80-144.12; P<0.0001). A secondary analysis was performed after excluding 25 patients emergently intubated in the Emergency Department for airway protection. In the logistic regression analysis controlling for age and NIHSS score, postprocedure extubation was still associated with higher odds of good outcomes (OR, 13.35; CI, 2.58-68.90; P=0.002). CONCLUSIONS: These findings indicate the importance of ventilation management and extubation after endovascular intervention under GA in patients with AIS.

Cortisol is More Important than Metanephrines in Driving Changes in Leukocyte Counts after Stroke.

BACKGROUND: There are notable changes in the number of white blood cells (WBCs) after stroke, but the primary mediators of these changes are unclear. In this study, we assessed the role of the neuroendocrine and sympathetic nervous systems in stroke-induced changes of WBCs within distinct leukocyte subsets, as well as the effect of these changes on stroke outcomes. METHODS: Patients were recruited within 72 hours after ischemic stroke; complete blood count with differential was obtained at set time points. The relationships among leukocyte numbers, cortisol, adrenocorticotropic hormone, interleukin-6, and metanephrines were assessed at 72 hours after stroke. Associations between abnormal leukocyte counts at 72 hours, poststroke infection, and 3-month outcomes were determined. RESULTS: A total of 114 subjects were enrolled. Severe stroke was associated with leukocytosis, neutrophilia, monocytosis, lymphopenia, and eosinopenia. At 72 hours after stroke, increased serum cortisol was independently associated with neutrophilia and lymphopenia. Abnormal leukocyte counts were not independently predictive of poststroke infection, but lymphopenia was associated with poor outcome (modified Rankin score >3) at 3 months after stroke (odds ratio = 22.86 [1.95, 267.65]; P = .01). CONCLUSIONS: Increased serum cortisol is independently associated with neutrophilia and lymphopenia after stroke. Lymphopenia is not an independent predictor of infections but is independently associated with worse outcome.

Added Value of Vessel Wall Magnetic Resonance Imaging for Differentiation of Nonocclusive Intracranial Vasculopathies.

BACKGROUND AND PURPOSE: Our goal is to determine the added value of intracranial vessel wall magnetic resonance imaging (IVWI) in differentiating nonocclusive vasculopathies compared with luminal imaging alone. METHODS: We retrospectively reviewed images from patients with both luminal and IVWI to identify cases with clinically defined intracranial vasculopathies: atherosclerosis (intracranial atherosclerotic disease), reversible cerebral vasoconstriction syndrome, and inflammatory vasculopathy. Two neuroradiologists blinded to clinical data reviewed the luminal imaging of defined luminal stenoses/irregularities and evaluated the pattern of involvement to make a presumed diagnosis with diagnostic confidence. Six weeks later, the 2 raters rereviewed the luminal imaging in addition to IVWI for the pattern of wall involvement, presence and pattern of postcontrast enhancement, and presumed diagnosis and confidence. Analysis was performed on per-lesion and per-patient bases. RESULTS: Thirty intracranial atherosclerotic disease, 12 inflammatory vasculopathies, and 12 reversible cerebral vasoconstriction syndrome patients with 201 lesions (90 intracranial atherosclerotic disease, 64 reversible cerebral vasoconstriction syndrome, and 47 inflammatory vasculopathy lesions) were included. For both per-lesion and per-patient analyses, there was significant diagnostic accuracy improvement with luminal imaging+IVWI when compared with luminal imaging alone (per-lesion: 88.8% versus 36.1%; P<0.001 and per-patient: 96.3% versus 43.5%; P<0.001, respectively). There was substantial interrater diagnostic agreement for luminal imaging+IVWI (κ=0.72) and only slight agreement for luminal imaging (κ=0.04). Although there was a significant correlation for both luminal and IVWI pattern of wall involvement with diagnosis, there was a stronger correlation for IVWI finding of lesion eccentricity and intracranial atherosclerotic disease diagnosis than for luminal imaging (κ=0.69 versus 0.18; P<0.001). CONCLUSIONS: IVWI can significantly improve the differentiation of nonocclusive intracranial vasculopathies when combined with traditional luminal imaging modalities.

Randomized trial of telephone versus in-person delivery of a brief psychosocial intervention in post-stroke depression.

BACKGROUND: A psychosocial behavioral intervention delivered in-person by advanced practice nurses has been shown effective in substantially reducing post-stroke depression (PSD). This follow-up trial compared the effectiveness of a shortened intervention delivered by either telephone or in-person to usual care. To our knowledge, this is the first of current behavioral therapy trials to expand the protocol in a new clinical sample. 100 people with Geriatric Depression Scores ≥ 11 were randomized within 4 months of stroke to usual care (N = 28), telephone intervention (N = 37), or in-person intervention (N = 35). Primary outcome was response [percent reduction in the Hamilton Depression Rating Scale (HDRS)] and remission (HDRS score < 10) at 8 weeks and 12 months post treatment. RESULTS: Intervention groups were combined for the primary analysis (pre-planned). The mean response in HDRS scores was 39% reduction for the combined intervention group (40% in-person; 38% telephone groups) versus 33% for the usual care group at 8 weeks (p = 0.3). Remission occurred in 37% in the combined intervention groups at 8 weeks versus 27% in the control group (p = 0.3) and 44% intervention versus 36% control at 12 months (p = 0.5). While favouring the intervention, these differences were not statistically significant. CONCLUSIONS: A brief psychosocial intervention for PSD delivered by telephone or in-person did not reduce depression significantly more than usual care. However, the comparable effectiveness of telephone and in-person follow-up for treatment of depression found is important given greater accessibility by telephone and mandated post-hospital follow-up for comprehensive stroke centers.

Labetalol Use Is Associated With Increased In-Hospital Infection Compared With Nicardipine Use in Intracerebral Hemorrhage.

BACKGROUND AND PURPOSE: Increased sympathetic tone causes hypertension after intracerebral hemorrhage, and blood pressure reduction has been studied as a way to decrease hemorrhage growth and improve outcomes. It is unknown if the antihypertensive used to achieve blood pressure goals influences either. Because sympatholytic drugs reduce death and infection in animal models, we hypothesized that labetalol would improve outcomes compared with nicardipine. METHODS: Prospective data from a single center were retrospectively reviewed. Patients receiving labetalol, nicardipine, or both during their first 3 days of hospitalization were included. Outcomes included in-hospital death; discharge modified Rankin Score >2; and in-hospital urinary tract infection, pneumonia, or bacteremia. Patients were compared with propensity scoring and analyzed with linear models adjusted for significant confounders. RESULTS: Of 1066 admissions, 525 were treated with labetalol or nicardipine and are included; 229 (43.6%) received labetalol, 107 (20.4%) received nicardipine, and 189 (36.0%) received both. Mortality and infection rates were 40.2% and 15.8%, respectively, 77.2% had a modified Rankin Score >2. After adjustment, compared with nicardipine alone, labetalol alone was associated with infection (odds ratio, 3.12; confidence interval, 1.27-7.64; P=0.013) but not when combined with nicardipine (odds ratio, 2.44; confidence interval, 0.98-6.07; P=0.055). Labetalol, with or without nicardipine, was not associated with death or discharge modified Rankin Score >2. CONCLUSIONS: Compared with nicardipine, labetalol was associated with increased in-hospital infections, but not mortality or modified Rankin Score >2. These findings do not support our hypothesis that labetalol use improves outcomes relative to nicardipine in intracerebral hemorrhage.

Poststroke Fatigue: Emerging Evidence and Approaches to Management: A Scientific Statement for Healthcare Professionals From the American Heart Association.

At least half of all stroke survivors experience fatigue; thus, it is a common cause of concern for patients, caregivers, and clinicians after stroke. This scientific statement provides an international perspective on the emerging evidence surrounding the incidence, prevalence, quality of life, and complex pathogenesis of poststroke fatigue. Evidence for pharmacological and nonpharmacological interventions for management are reviewed, as well as the effects of poststroke fatigue on both stroke survivors and caregivers.

Increased infections with ß-blocker use in ischemic stroke, a ß2-receptor mediated process?

Strokes promote immunosuppression, partially from increased sympathetic activity. Altering sympathetic drive with ß-blockers has variably been shown to improve stroke outcomes. This study adds to this literature using propensity score matching to limit confounding and by examining the effects of selective and non-selective ß-blockers. Prospective data from acute ischemic stroke admissions at a single center from July 2010-June 2015 were analyzed. Outcomes included infection (urinary tract infection [UTI], pneumonia, or bacteremia), discharge modified Rankin Score (mRS), and in-hospital death. Any selective and non-selective ß-blocker use during the first 3 days of admission were investigated with propensity score matching. A sensitivity analysis was also performed. This study included 1431 admissions. Any ß-blocker use was associated with increased infections (16.4 vs. 10.7%, p = 0.030). Non-selective ß-blocker use was associated with increased infections (18.9 vs. 9.7%, p = 0.005) and UTIs (13.0 vs. 5.5%, p = 0.009). Selective ß-blocker use was not associated with infection. There were no associations between ß-blocker use and in-hospital death or discharge mRS. In the sensitivity analysis, the association between non-selective ß-blocker use and urinary tract infections persisted (12.5 vs. 4.2%, p = 0.044). No associations with death or mRS were found. Early ß-blocker use after ischemic stroke may increase the risk of infection but did not change disability or mortality risk. The mechanism may be mediated by ß2-adrenergic receptor antagonism given the different effects seen with selective versus non-selective ß-blocker use.
