Prospective, Multicenter, Controlled Trial of Mobile Stroke Units.

BACKGROUND: Mobile stroke units (MSUs) are ambulances with staff and a computed tomographic scanner that may enable faster treatment with tissue plasminogen activator (t-PA) than standard management by emergency medical services (EMS). Whether and how much MSUs alter outcomes has not been extensively studied. METHODS: In an observational, prospective, multicenter, alternating-week trial, we assessed outcomes from MSU or EMS management within 4.5 hours after onset of acute stroke symptoms. The primary outcome was the score on the utility-weighted modified Rankin scale (range, 0 to 1, with higher scores indicating better outcomes according to a patient value system, derived from scores on the modified Rankin scale of 0 to 6, with higher scores indicating more disability). The main analysis involved dichotomized scores on the utility-weighted modified Rankin scale (≥0.91 or <0.91, approximating scores on the modified Rankin scale of ≤1 or >1) at 90 days in patients eligible for t-PA. Analyses were also performed in all enrolled patients. RESULTS: We enrolled 1515 patients, of whom 1047 were eligible to receive t-PA; 617 received care by MSU and 430 by EMS. The median time from onset of stroke to administration of t-PA was 72 minutes in the MSU group and 108 minutes in the EMS group. Of patients eligible for t-PA, 97.1% in the MSU group received t-PA, as compared with 79.5% in the EMS group. The mean score on the utility-weighted modified Rankin scale at 90 days in patients eligible for t-PA was 0.72 in the MSU group and 0.66 in the EMS group (adjusted odds ratio for a score of ≥0.91, 2.43; 95% confidence interval [CI], 1.75 to 3.36; P<0.001). Among the patients eligible for t-PA, 55.0% in the MSU group and 44.4% in the EMS group had a score of 0 or 1 on the modified Rankin scale at 90 days. Among all enrolled patients, the mean score on the utility-weighted modified Rankin scale at discharge was 0.57 in the MSU group and 0.51 in the EMS group (adjusted odds ratio for a score of ≥0.91, 1.82; 95% CI, 1.39 to 2.37; P<0.001). Secondary clinical outcomes generally favored MSUs. Mortality at 90 days was 8.9% in the MSU group and 11.9% in the EMS group. CONCLUSIONS: In patients with acute stroke who were eligible for t-PA, utility-weighted disability outcomes at 90 days were better with MSUs than with EMS.

Average duration of prior treatment lines predicts clinical benefit to eribulin chemotherapy in patients with metastatic breast cancer.

PURPOSE: The aim of this study was to identify factors associated with progression-free survival (PFS) and overall survival (OS) in patients with metastatic breast cancer (MBC) treated with eribulin in a real-world setting, to improve information provision in those considering treatment. METHODS: Patients treated with eribulin for MBC at The Christie NHS Foundation Trust, Manchester, UK, between August 2011 and December 2018 were included (n = 439). Data were collected by retrospective review of medical records and electronic prescribing systems. Factors such as biological subtype, distant recurrence-free interval, previous lines of chemotherapy and the 'average duration of previous treatment lines' (ADPT) (calculated as: (date of initiation of eribulin-date of MBC) / the number of previous treatment lines in the metastatic setting) were evaluated for prognostic impact using Cox proportional hazards regression. RESULTS: In the full cohort, the median PFS and OS were 4.1 months (95% CI 3.7-4.4) and 8.6 months (95% CI 7.4-9.8), respectively. Outcomes were significantly inferior for those with triple-negative breast cancer (TNBC) (n = 92); PFSTNBC: 2.4 months (95% CI 2.1-3.0), p = < 0.001 and OSTNBC: 5.4 months (95% CI 4.6-6.6), p = < 0.001. ADPT was the only factor other than subtype significantly associated with PFS and OS. Longer ADPT was also significantly associated with PFS and OS in those with TNBC. For example, women in the lowest ADPT tertile (< 5.0 months) achieved a median OS of only 4.3 months, whereas those in the upper ADPT tertile (> 8.7 months) had a median OS of 12.1 months (p = 0.004). CONCLUSION: Our results indicate that the ADPT lines is an important factor when predicting the outcome with eribulin chemotherapy in a palliative setting and that quantitative guidance on the likely PFS and OS with treatment can be provided using ADPT. Validation in additional cohorts is warranted.

Eribulin Treatment for Patients with Metastatic Breast Cancer: The UK Experience - A Multicenter Retrospective Study.

INTRODUCTION: This study examined real-world data from patients who received eribulin for metastatic breast cancer (MBC) collected from 14 hospitals across the UK. METHODS: Anonymized data were collected retrospectively from patients with MBC who had received eribulin. The data included the hormone-receptor status, histological diagnosis, age, prior chemotherapy, response to eribulin, progression-free survival (PFS), and overall survival (OS). RESULTS: Among 577 patients analyzed, the median age was 56 years, and most patients (73%) were estrogen-receptor positive. The median OS was 288 days (95% confidence interval [CI]: 261-315), and the PFS was 117 days (95% CI: 105-129). The median OS was higher among older patients (≥65 vs. <65 years: 325 days [95% CI: 264-385] vs. 285 days [95% CI: 252-317]; p = 0.028). The median OS was also higher in patients who received eribulin after fewer prior lines of chemotherapy (≤2 vs. >2 prior: 328 days [95% CI: 264-385] vs. 264 days [95% CI: 229-298]; p = 0.042). DISCUSSION/CONCLUSION: These retrospective data suggest that eribulin can be successfully used in older patients with MBC. Eribulin treatment was more effective in earlier-line settings, which, while predictable, supports consideration of eribulin as a second-line treatment option.

Eribulin for the treatment of advanced breast cancer: A prospective observational registry study.

OBJECTIVE: Eribulin treatment improved overall survival with predictable toxicities in phase 3 trials of patients with previously treated, locally advanced/metastatic breast cancer. This study (NCT02443428) prospectively observed eribulin-treated patients in real-world clinical practice. METHODS: This observational multicentre registry study enrolled 76 patients with locally advanced/metastatic breast cancer who had ≤2 prior chemotherapeutic regimens for advanced disease. Eribulin was administered at a 1.23 mg/m2 dose (days 1 and 8 of every 21-day cycle). Adverse events (AEs) were monitored and effectiveness was assessed per local practice. RESULTS: AEs occurred in 98.7% of patients; 88.2% had eribulin-related AEs. The most common AEs were fatigue (64.5%), alopecia (36.8%), nausea (35.5%) and constipation (30.3%). Serious AEs occurred in 42.1% of patients. The most common grade 3/4 AEs were neutropenia (9.2%), febrile neutropenia (9.2%), dyspnoea (5.3%) and pleural effusion (5.3%). No fatal AEs occurred. Dose reductions occurred in 31.6% of patients, 42.1% experienced dose delays and 9.2% discontinued due to worsening condition. There were complete responses in 2.6% and partial responses in 15.8% of patients. Median time to progression and overall survival were 4.0 and 8.3 months, respectively. CONCLUSION: Eribulin was well tolerated in real-world clinical practice, comparable to safety and effectiveness reported in other clinical trials.

Multifocal transcranial stimulation in chronic ischemic stroke: A phase 1/2a randomized trial.

BACKGROUND AND PURPOSE: Repetitive transcranial magnetic stimulation (rTMS) may promote recovery of motor function after stroke by inducing functional reorganization of cortical circuits. The objective of this study was to examine whether multifocal cortical stimulation using a new wearable transcranial rotating permanent magnet stimulator (TRPMS) can promote recovery of motor function after stroke by inducing functional reorganization of cortical circuits. METHODS: Thirty30 patients with chronic ischemic stroke and stable unilateral weakness were enrolled in a Phase 1/2a randomized double-blind sham-controlled clinical trial to evaluate safety and preliminary efficacy. Bilateral hemispheric stimulation was administered for 20 sessions 40 min each over 4 weeks. The primary efficacy endpoint was the change in functional MRI BOLD activation immediately after end of treatment. Secondary efficacy endpoints were clinical scales of motor function, including the Fugl-Meyer motor arm score, ARAT, grip strength, pinch strength, gait velocity, and NIHSS. RESULTS: TRPMS treatment was well-tolerated with no device-related adverse effects. Active treatment produced a significantly greater increase in the number of active voxels on fMRI than sham treatment (median +48.5 vs -30, p = 0.038). The median active voxel number after active treatment was 8.8-fold greater than after sham (227.5 vs 26, p = 0.016). Although the statistical power was inadequate to establish clinical endpoint benefits, numerical improvements were demonstrated in 5 of 6 clinical scales of motor function. The treatment effects persisted over a 3-month duration of follow-up. CONCLUSIONS: Multifocal bilateral TRPMS was safe and showed significant fMRI changes suggestive of functional reorganization of cortical circuits in patients with chronic ischemic stroke. A larger randomized clinical trial is warranted to verify recovery of motor function.

Systemic anti-cancer therapy delivery in the home: a service model.

The Christie NHS Foundation Trust is a leader in adapting patient care in response to treatment advances and new patient-centred care/efficiency initiatives. Due to extended waiting times in cancer clinics, The Christie developed an at-home treatment service to help reduce the pressure on clinics and improve patient experience. This article provides a detailed examination of the requirements necessary to successfully develop a home service for the delivery of systemic anticancer treatment. The authors discuss the criteria used to identify suitable at-home treatments, as well as necessary resources and equipment. The success of the Christie at Home service was examined using a patient survey to assess the standard of this care. Details are given regarding the challenges of implementing a homecare service and potential future challenges. As an example, systemic treatment with eribulin as a 'Christie at Home' therapy demonstrates the practicalities of introduction of new therapies in a homecare service.

Effect of Single-Fraction vs Multifraction Radiotherapy on Ambulatory Status Among Patients With Spinal Canal Compression From Metastatic Cancer: The SCORAD Randomized Clinical Trial.

Importance: Malignant spinal canal compression, a major complication of metastatic cancer, is managed with radiotherapy to maintain mobility and relieve pain, although there is no standard radiotherapy regimen. Objective: To evaluate whether single-fraction radiotherapy is noninferior to 5 fractions of radiotherapy. Design, Setting, and Participants: Multicenter noninferiority randomized clinical trial conducted in 42 UK and 5 Australian radiotherapy centers. Eligible patients (n = 686) had metastatic cancer with spinal cord or cauda equina compression, life expectancy greater than 8 weeks, and no previous radiotherapy to the same area. Patients were recruited between February 2008 and April 2016, with final follow-up in September 2017. Interventions: Patients were randomized to receive external beam single-fraction 8-Gy radiotherapy (n = 345) or 20 Gy of radiotherapy in 5 fractions over 5 consecutive days (n = 341). Main Outcomes and Measures: The primary end point was ambulatory status at week 8, based on a 4-point scale and classified as grade 1 (ambulatory without the use of aids and grade 5 of 5 muscle power) or grade 2 (ambulatory using aids or grade 4 of 5 muscle power). The noninferiority margin for the difference in ambulatory status was -11%. Secondary end points included ambulatory status at weeks 1, 4, and 12 and overall survival. Results: Among 686 randomized patients (median [interquartile range] age, 70 [64-77] years; 503 (73%) men; 44% had prostate cancer, 19% had lung cancer, and 12% had breast cancer), 342 (49.8%) were analyzed for the primary end point (255 patients died before the 8-week assessment). Ambulatory status grade 1 or 2 at week 8 was achieved by 115 of 166 (69.3%) patients in the single-fraction group vs 128 of 176 (72.7%) in the multifraction group (difference, -3.5% [1-sided 95% CI, -11.5% to ∞]; P value for noninferiority = .06). The difference in ambulatory status grade 1 or 2 in the single-fraction vs multifraction group was -0.4% (63.9% vs 64.3%; [1-sided 95% CI, -6.9 to ∞]; P value for noninferiority = .004) at week 1, -0.7% (66.8% vs 67.6%; [1-sided 95% CI, -8.1 to ∞]; P value for noninferiority = .01) at week 4, and 4.1% (71.8% vs 67.7%; [1-sided 95% CI, -4.6 to ∞]; P value for noninferiority = .002) at week 12. Overall survival rates at 12 weeks were 50% in the single-fraction group vs 55% in the multifraction group (stratified hazard ratio, 1.02 [95% CI, 0.74-1.41]). Of the 11 other secondary end points that were analyzed, the between-group differences were not statistically significant or did not meet noninferiority criterion. Conclusions and Relevance: Among patients with malignant metastatic solid tumors and spinal canal compression, a single radiotherapy dose, compared with a multifraction dose delivered over 5 days, did not meet the criterion for noninferiority for the primary outcome (ambulatory at 8 weeks). However, the extent to which the lower bound of the CI overlapped with the noninferiority margin should be considered when interpreting the clinical importance of this finding.

Safety and Feasibility of Argatroban, Recombinant Tissue Plasminogen Activator, and Intra-Arterial Therapy in Stroke (ARTSS-IA Study).

BACKGROUND: A randomized trial of concurrent recombinant tissue-type plasminogen activator (r-tPA) + thrombin-inhibition with Argatroban in stroke patients recently demonstrated safety and signal of efficacy compared to r-tPA alone, but patients having endovascular therapy (EVT) were excluded. The current study intended to study feasibility and safety of concurrent r-tPA and Argatroban in patients undergoing EVT. METHODS: We conducted a single-arm, feasibility, and safety study of patients that received standard-dose r-tPA, had intracranial large vessel occlusions, and underwent EVT within 6 hours of stroke onset. During r-tPA, a 100 µg/kg Argatroban bolus, followed by 12-hour infusion, targeted an activated Partial Thromboplastin Time (aPTT) 2.25 timesbaseline. Feasibility was defined as ability to combine treatments without EVT time-metric delays, compared to cotemporaneous r-tPA + EVT treatments. Safety was incidence of symptomatic intracerebral hemorrhage (sICH), systemic hemorrhage, or EVT complications. RESULTS: All preplanned 10 patients were enrolled. Arterial occlusions were middle cerebral artery (n = 8), internal carotid artery (n = 1), and posterior cerebral artery (n = 1). All received Argatroban before EVT and completed infusions. There were no delays in time-metrics compared to nonstudy patients during the same period. Nine patients achieved excellent angiographic reperfusion (Thrombolysis In Cerebral Ischemia [TICI] ≥2b); with 7 complete (TICI = 3). There were no sICH, systemic hemorrhage, or EVT complications. At 90 days, 6 (60%) patients had a modified Rankin Scale of 0-2 and none died. CONCLUSIONS: In patients treated with r-tPA and EVT, concomitant Argatroban is feasible, does not delay EVT provision, produces high rates of recanalization, is probably safe, and warrants further study.

Clinical Course and Outcomes of Small Supratentorial Intracerebral Hematomas.

BACKGROUND AND PURPOSE: Intracerebral hemorrhage (ICH) volume, particularly if ≥30 mL, is a major determinant of poor outcome. We used a multinational ICH data registry to study the characteristics, course, and outcomes of supratentorial hematomas with volumes <30 mL. METHODS: Basic characteristics, clinical and radiological course, and 30-day outcomes of these patients were recorded. Outcomes were categorized as early neurological deterioration (END), hematoma expansion, Glasgow Outcome Scale (GOS), and in-hospital death. Poor outcome was defined as composite of in-hospital death and severe disability (GOS ≤ 3). Comparison was conducted based on hemorrhage location. Logistic regression using dichotomized outcome scales was applied to determine predictors of poor outcome. RESULTS: Among 375 cases of supratentorial ICH with volumes <30 mL, expansion and END rates were 19.2% and 7.5%, respectively. Hemorrhage growth was independently associated with END (odds ratio: 28.7, 95% confidence interval [CI]: 8.51-96.5; P < .0001). Expansion rates did not differ according to ICH location. Overall, 13.9% (exact binomial 95% CI: 10.5-17.8) died in the hospital and 29.1% (CI: 24.5-34.0) had severe disability at 30 days; there was a cumulative poor outcome rate of 42.9% (CI: 37.9-48.1). Age, admission Glasgow Coma Scale, intraventricular extension, and END were independently associated with poor outcome. There was no difference in poor outcome rates between lobar and deep locations (40.2% versus 43.8%, P = .56). CONCLUSION: Patients with supratentorial ICH <30 mL have high rates of poor outcome at 30 days, regardless of location. Nearly 1 in 5 hematomas <30 mL expands, leading to END or death.

Cannabis Use and Outcomes in Patients With Aneurysmal Subarachnoid Hemorrhage.

BACKGROUND AND PURPOSE: The incidence of cannabis use in patients with aneurysmal subarachnoid hemorrhage (aSAH) and its impact on morbidity, mortality, and outcomes are unknown. Our objective was to evaluate the relationship between cannabis use and outcomes in patients with aSAH. METHODS: Records of consecutive patients admitted with aSAH between 2010 and 2015 were reviewed. Clinical features and outcomes of aSAH patients with negative urine drug screen and cannabinoids-positive (CB+) were compared. Regression analyses were used to assess for associations. RESULTS: The study group consisted of 108 patients; 25.9% with CB+. Delayed cerebral ischemia was diagnosed in 50% of CB+ and 23.8% of urine drug screen negative patients (P=0.01). CB+ was independently associated with development of delayed cerebral ischemia (odds ratio, 2.68; 95% confidence interval, 1.03-6.99; P=0.01). A significantly higher number of CB+ than urine drug screen negative patients had poor outcome (35.7% versus 13.8%; P=0.01). In univariate analysis, CB+ was associated with the composite end point of hospital mortality/severe disability (odds ratio, 2.93; 95% confidence interval, 1.07-8.01; P=0.04). However, after adjusting for other predictors, this effect was no longer significant. CONCLUSIONS: We offer preliminary data that CB+ is independently associated with delayed cerebral ischemia and possibly poor outcome in patients with aSAH. Our findings add to the growing evidence on the association of cannabis with cerebrovascular risk.

Risk of intracerebral hemorrhage in HIV/AIDS: a systematic review and meta-analysis.

Evidence for the association and the increased risk of stroke with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is growing. Recent studies have reported on HIV infection as a potent risk factor for intracerebral hemorrhage (ICH). We used the pooled results from case-control studies to conduct a systematic review and a meta-analysis in order to evaluate the risk of ICH with HIV/AIDS. Our systematic review and meta-analysis was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses algorithm of all available case-control studies that reported on the risk of ICH in patients with HIV/AIDS. Five eligible studies were identified, totaling 5,310,426 person-years studied over various periods that ranged from 1985 to 2010. There were a total of 724 cases of ICH, 138 with HIV/AIDS. HIV-infected ICH patients were in average younger. Pooled crude incidence rate ratio (IRR) for ICH in HIV/AIDS patients was 3.40 (95 % confidence intervals [CI] 1.44-8.04; p = 0.005, random-effects model). Clinical AIDS was associated with a higher IRR of ICH (11.99, 95 % CI 2.84-50.53; p = 0.0007) than HIV+ status without AIDS (1.73, 95 % CI 1.39-2.16; p < 0.0001). Patients with CD4+ lymphocyte count <200 cells/mm3 were similarly at a higher risk. Antiretroviral therapy did not seem to increase the risk of ICH. The available evidence suggests that HIV/AIDS is an important risk factor for ICH, particularly in younger HIV-infected patients and those with advanced disease.

Early Hypoalbuminemia is an Independent Predictor of Mortality in Aneurysmal Subarachnoid Hemorrhage.

BACKGROUND: Hypoalbuminemia has been identified as a predictor of morbidity and mortality in critically ill patients. There is very little data on the significance and the prognostic value of hypoalbuminemia in patients with aneurysmal subarachnoid hemorrhage (aSAH). This study analyzed the impact of hypoalbuminemia on patient presentation, complications, and outcomes. METHODS: Records of patients admitted with aSAH were examined. Data on baseline characteristics, prevalence of delayed cerebral ischemia, and discharge outcomes were collected. Multivariable logistic regression analysis was performed to assess for associations. RESULTS: One-hundred and forty-two patients comprised the study cohort (mean age 54.6 ± 13.4), among which 45 (31.5 %) presented with hypoalbuminemia. No difference in baseline characteristics was noted between patients with hypoalbuminemia and those with normal serum albumin. The overall hospital mortality rate was significantly higher in patients with hypoalbuminemia, compared to those with normal albumin (28.9 % vs. 11.3 %; p = 0.04). Hypoalbuminemia was neither associated with delayed cerebral ischemia nor disability at discharge, but independently associated with in-hospital death (odds ratio: 4.26, 95 % confidence interval: 1.09-16.68; p = 0.04). CONCLUSION: In patients with aSAH, early hypoalbuminemia is an independent predictor of hospital mortality but not disability at discharge.

Focal Neurological Deficit at Onset of Aneurysmal Subarachnoid Hemorrhage: Frequency and Causes.

BACKGROUND AND AIM: Focal neurological deficit (FND) is a recognized presenting symptom of aneurysmal subarachnoid hemorrhage (SAH). However, little is known on how often aneurysmal SAH patients present with FND and what the responsible mechanisms are. The aim of this study was to examine the frequency and causes of FND at onset in aneurysmal SAH. METHODS: We reviewed the records of consecutive aneurysmal SAH patients over 5 years and identified those who presented with FND. We developed several potential mechanisms for FND based on consensus between 2 separate evaluating neurologists. We then compared the characteristics of aneurysmal SAH patients who presented with and without FND. Logistic regression models were used to assess for association of FND with poor outcome. RESULTS: Of a total of 213 patients, 10.3% presented with FND. The junction of the internal carotid and posterior communicating arteries was the most common aneurysm location in patients with FND (36.4%). Causes of FND at presentation were intraparenchymal hematoma in 45.5%, early cerebral infarction in 22.7%, parenchymal compression by subarachnoid thrombus in 18.2%, and seizure with Todd's paralysis in 13.6%. Patients with FND were older (P = .001) and had higher rates of in-hospital death and severe disability at discharge (P < .0001), compared to those without focal deficit. FND was independently associated with poor outcome (odds ratio: 4.62, confidence interval: 1.41-15.14; P = .01). CONCLUSION: One in every 10 aneurysmal SAH patients presents with FND. FND at presentation has diverse mechanisms, is not associated with a specific aneurysm location, and is independently associated with poor outcome.

Older Stroke Patients with High Stroke Scores Have Delayed Door-To-Needle Times.

INTRODUCTION: The timely administration of intravenous (IV) tissue plasminogen activator (t-PA) to acute ischemic stroke patients from the period of symptom presentation to treatment, door-to-needle (DTN) time, is an important focus for quality improvement and best clinical practice. METHODS: A retrospective review of our Get With The Guidelines database was performed for a 5-hospital telestroke network for the period between January 2010 and January 2015. All acute ischemic stroke patients who were triaged in the emergency departments connected to the telestroke network and received IV t-PA were included. Optimal DTN time was defined as less than 60 minutes. Logistic regression was performed with clinical variables associated with DTN time. Age and National Institutes of Health Stroke Scale (NIHSS) score were categorized based on clinically significant cutoffs. RESULTS: Six-hundred and fifty-two patients (51% women, 46% White, 45% Hispanic, and 8% Black) were included in this study. The mean age was 70 years (range 29-98). Of the variables analyzed, only arrival mode, initial NIHSS score, and the interaction between age and initial NIHSS score were significant. DTN time more than or equal to 60 minutes was most common in patients aged more than 80 years with NIHSS score higher than 10. CONCLUSIONS: The cause of DTN time delay for older patients with higher NIHSS score is unclear but was not related to presenting blood pressure or arrival mode. Further study of this subgroup is important to reduce overall DTN times.

Clotting factors to treat thrombolysis-related symptomatic intracranial hemorrhage in acute ischemic stroke.

BACKGROUND: Symptomatic intracranial hemorrhage (sICH) occurs uncommonly after ischemic stroke therapy with tissue plasminogen activator (tPA). Clotting factor administration may be a treatment option. OBJECTIVE: To determine if treatment with clotting factors (fresh frozen plasma [FFP] or cryoprecipitate) was associated with improved outcomes in sICH. METHODS: We conducted a retrospective cohort study within University of Texas at Houston Stroke registry involving consecutive patients from February 1, 2007, to June 30, 2011, with tPA-related sICH, including cases with subsequent intra-arterial therapy. Outcomes were Modified Rankin Scale (mRS) score at discharge, death, and hematoma expansion. RESULTS: Of 921 patients treated with tPA, 48 (5.2%) had sICH and 45 met criteria for the study. Nineteen patients received clotting factors (42.2%; 18 received FFP and 7 received cryoprecipitate), whereas 26 (57.8%) patients received conservative management without clotting factors. None of the patients treated with clotting factors and only 2 of those who did not receive clotting factors had a good outcome, mRS score of 2 or less. All the patients treated with clotting factors and most of those not treated were left bedridden or dead (mRS score 4-6), 19 (100%) versus 22 (85%). Mortality was 9 (47.4%) versus 9 (34.6%), respectively. There was no difference in hematoma expansion between the 2 groups. CONCLUSIONS: We found no evidence that treatment for sICH with clotting factors has a favorable effect on clinical or radiological outcomes. However, the sample was small because of the low frequency of sICH. New treatments are urgently needed for this uncommon yet serious condition.

Independent validation of genes and polymorphisms reported to be associated with radiation toxicity: a prospective analysis study.

BACKGROUND: Several studies have reported associations between radiation toxicity and single nucleotide polymorphisms (SNPs) in candidate genes. Few associations have been tested in independent validation studies. This prospective study aimed to validate reported associations between genotype and radiation toxicity in a large independent dataset. METHODS: 92 (of 98 attempted) SNPs in 46 genes were successfully genotyped in 1613 patients: 976 received adjuvant breast radiotherapy in the Cambridge breast IMRT trial (ISRCTN21474421, n=942) or in a prospective study of breast toxicity at the Christie Hospital, Manchester, UK (n=34). A further 637 received radical prostate radiotherapy in the MRC RT01 multicentre trial (ISRCTN47772397, n=224) or in the Conventional or Hypofractionated High Dose Intensity Modulated Radiotherapy for Prostate Cancer (CHHiP) trial (ISRCTN97182923, n=413). Late toxicity was assessed 2 years after radiotherapy with a validated photographic technique (patients with breast cancer only), clinical assessment, and patient questionnaires. Association tests of genotype with overall radiation toxicity score and individual endpoints were undertaken in univariate and multivariable analyses. At a type I error rate adjusted for multiple testing, this study had 99% power to detect a SNP, with minor allele frequency of 0·35, associated with a per allele odds ratio of 2·2. FINDINGS: None of the previously reported associations were confirmed by this study, after adjustment for multiple comparisons. The p value distribution of the SNPs tested against overall toxicity score was not different from that expected by chance. INTERPRETATION: We did not replicate previously reported late toxicity associations, suggesting that we can essentially exclude the hypothesis that published SNPs individually exert a clinically relevant effect. Continued recruitment of patients into studies within the Radiogenomics Consortium is essential so that sufficiently powered studies can be done and methodological challenges addressed.

Stroke severity mediates the effect of socioeconomic disadvantage on poor outcomes among patients with intracerebral hemorrhage.

Background: Socioeconomic deprivation drives poor functional outcomes after intracerebral hemorrhage (ICH). Stroke severity and background cerebral small vessel disease (CSVD) burden have each been linked to socioeconomic status and independently contribute to worse outcomes after ICH, providing distinct, plausible pathways for the effects of deprivation. We investigate whether admission stroke severity or cerebral small vessel disease (CSVD) mediates the effect of socioeconomic deprivation on 90-day functional outcomes. Methods: Electronic medical record data, including demographics, treatments, comorbidities, and physiological data, were analyzed. CSVD burden was graded from 0 to 4, with severe CSVD categorized as ≥3. High deprivation was assessed for patients in the top 30% of state-level area deprivation index scores. Severe disability or death was defined as a 90-day modified Rankin Scale score of 4-6. Stroke severity (NIH stroke scale (NIHSS)) was classified as: none (0), minor (1-4), moderate (5-15), moderate-severe (16-20), and severe (21+). Univariate and multivariate associations with severe disability or death were determined, with mediation evaluated through structural equation modelling. Results: A total of 677 patients were included (46.8% female; 43.9% White, 27.0% Black, 20.7% Hispanic, 6.1% Asian, 2.4% Other). In univariable modelling, high deprivation (odds ratio: 1.54; 95% confidence interval: [1.06-2.23]; p = 0.024), severe CSVD (2.14 [1.42-3.21]; p < 0.001), moderate (8.03 [2.76-17.15]; p < 0.001), moderate-severe (32.79 [11.52-93.29]; p < 0.001), and severe stroke (104.19 [37.66-288.12]; p < 0.001) were associated with severe disability or death. In multivariable modelling, severe CSVD (3.42 [1.75-6.69]; p < 0.001) and moderate (5.84 [2.27-15.01], p < 0.001), moderate-severe (27.59 [7.34-103.69], p < 0.001), and severe stroke (36.41 [9.90-133.85]; p < 0.001) independently increased odds of severe disability or death; high deprivation did not. Stroke severity mediated 94.1% of deprivation's effect on severe disability or death (p = 0.005), while CSVD accounted for 4.9% (p = 0.524). Conclusion: CSVD contributed to poor functional outcome independent of socioeconomic deprivation, while stroke severity mediated the effects of deprivation. Improving awareness and trust among disadvantaged communities may reduce admission stroke severity and improve outcomes.

Intravenous autologous bone marrow mononuclear cells for ischemic stroke.

OBJECTIVE: Cellular therapy is an investigational approach for stroke. Mononuclear cells (MNCs) from the bone marrow reduce neurological deficits in animal stroke models. We determined if autologous MNC infusion was feasible and safe in patients with ischemic stroke. METHODS: We conducted an open-label prospective study of a bone marrow harvest followed by readministration of autologous MNCs in 10 patients, 18 to 80 years old, with acute middle cerebral artery ischemic stroke. Bone marrow was aspirated from the iliac crest, and MNCs were separated at a Good Manufacturing Practices facility and administered intravenously up to a maximum of 10 million cells/kg. The harvest and infusion had to occur between 24 and 72 hours after stroke. Patients were monitored for 6 months. RESULTS: Bone marrow aspiration was successfully completed in all patients. Eight received 10 million cells/kg, and 2 received ≥7 million cells/kg. There were no significant adverse events related to harvest or infusion. Two patients had infarct expansion between enrollment and harvest and underwent hemicraniectomy after cell infusion. One patient died at 40 days due to a pulmonary embolism related to the stroke. There were no study-related severe adverse events. Median National Institutes of Health Stroke Scale score was 13 before harvest, 8 at 7 days, and 3 at 6 months. At 6 months, all surviving patients had shifted down by at least 1 point on the modified Rankin Scale compared to day 7. Seven of 10 patients achieved a Barthel Index ≥90. INTERPRETATION: This study suggests that a bone marrow harvest and reinfusion of autologous MNCs were safe and feasible in acute stroke patients.

Acute ischemic stroke treated with intravenous tissue plasminogen activator in a patient taking dabigatran with radiographic evidence of recanalization.

Dabigatran etexelate is a new oral direct thrombin inhibitor that has been approved by the US Food and Drug Administration to prevent stroke in patients with nonvalvular atrial fibrillation. A 51-year-old man with a history of atrial fibrillation who was taking dabigatran presented with an acute ischemic stroke. The patient had a normal international normalized ratio, activated partial thromboplastin time, and an elevated thrombin time of 26.4 seconds. Recanalization of the middle cerebral artery with intravenous tissue plasminogen activator was apparent on digital subtraction angiography, and there was no evidence of intracerebral hemorrhage on the repeat computed tomographic scan. This is the first report of a patient who was taking dabigatran etexilate and who had an ischemic stroke caused by a middle cerebral artery occlusion, with an elevated thrombin time and radiographic recanalization with intravenous tissue plasminogen activator without evidence of hemorrhagic transformation.

A randomised, pragmatic clinical trial of ACUpuncture plus standard care versus standard care alone FOr Chemotherapy Induced peripheral Neuropathy (ACUFOCIN).

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) is a dose limiting toxicity posing a major clinical challenge for managing patients receiving specific chemotherapy regimens (e.g., Taxanes). There is a growing body of literature suggesting acupuncture can improve CIPN symptoms. The purpose of the ACUFOCIN trial was to collect preliminary data on the safety, feasibility, acceptability and initial effectiveness of acupuncture as a treatment for CIPN, comparing use of acupuncture plus standard care (Acupuncture) against standard care alone (Control). METHOD: At a tertiary cancer centre, a pragmatic, randomised, parallel group design study was used to investigate the effectiveness of a 10-week course of acupuncture. Participants experiencing CIPN of ≥ Grade II, recording a 'Most Troublesome' CIPN symptom score of ≥3 using the "Measure Yourself Medical Outcome Profile" (MYMOP 2), were randomised to 'Acupuncture' or 'Control' arms. Clinicians were blinded to allocated groups, however as it was not possible to blind participants, it cannot be guaranteed they did not disclose study allocation within their clinic assessments. The primary outcome measure was the number of patients reporting a ≥ 2-point improvement (success) in their MYMOP2 score at week 10. 100 participants (120 to allow for attrition) were required for a hypothesised improvement in success proportions from 30% to 55% using a primary analysis model with logistic regression adjusted for stratification factors and baseline MYMOP2 scores. Feasibility and acceptability of study design was addressed through percentage return of primary outcome, retention rate and a nested qualitative study. RESULTS: Primary MYMOP2 outcome data at week 10 was available for 108/120 randomised participants; this is greater than the 100 participants required to adequately power the study. There were 36/53 (68%) successes in 'Acupuncture' compared to 18/55 (33%) in 'Control'. Beneficial effects were seen in the secondary outcome data, including clinicians' grading of neuropathy, EORTC, QLQ-CIPN20, QLQ-C30 summary scores and patient reported pain scores. There were no serious adverse events reported within the study and only 16 acupuncture associated events, none of which required intervention. CONCLUSION: A 10-week course of acupuncture resulted in measurable improvement in participants symptoms of CIPN. The results warrant further investigation.
