Pharyngeal electrical stimulation for neurogenic dysphagia following stroke, traumatic brain injury or other causes: Main results from the PHADER cohort study.

BACKGROUND: Neurogenic dysphagia is common and has no definitive treatment. We assessed whether pharyngeal electrical stimulation (PES) is associated with reduced dysphagia. METHODS: The PHAryngeal electrical stimulation for treatment of neurogenic Dysphagia European Registry (PHADER) was a prospective single-arm observational cohort study. Participants were recruited with neurogenic dysphagia (comprising five groups - stroke not needing ventilation; stroke needing ventilation; ventilation acquired; traumatic brain injury; other neurological causes). PES was administered once daily for three days. The primary outcome was the validated dysphagia severity rating scale (DSRS, score best-worst 0-12) at 3 months. FINDINGS: Of 255 enrolled patients from 14 centres in Austria, Germany and UK, 10 failed screening. At baseline, mean (standard deviation) or median [interquartile range]: age 68 (14) years, male 71%, DSRS 11·4 (1·7), time from onset to treatment 32 [44] days; age, time and DSRS differed between diagnostic groups. Insertion of PES catheters was successfully inserted in 239/245 (98%) participants, and was typically easy taking 11·8 min. 9 participants withdrew before the end of treatment. DSRS improved significantly in all dysphagia groups, difference in means (95% confidence intervals, CI) from 0 to 3 months: stroke (n = 79) -6·7 (-7·8, -5·5), ventilated stroke (n = 98) -6·5 (-7·6, -5·5); ventilation acquired (n = 35) -6·6 (-8·4, -4·8); traumatic brain injury (n = 24) -4·5 (-6·6, -2·4). The results for DSRS were mirrored for instrumentally assessed penetration aspiration scale scores. DSRS improved in both supratentorial and infratentorial stroke, with no difference between them (p = 0·32). In previously ventilated participants with tracheotomy, DSRS improved more in participants who could be decannulated (n = 66) -7·5 (-8·6, -6·5) versus not decannulated (n = 33) -2·1 (-3·2, -1·0) (p<0·001). 74 serious adverse events (SAE) occurred in 60 participants with pneumonia (9·2%) the most frequent SAE. INTERPRETATION: In patients with neurogenic dysphagia, PES was safe and associated with reduced measures of dysphagia and penetration/aspiration. FUNDING: Phagenesis Ltd.

Prognostic Value of Inflammatory and Cardiovascular Biomarkers for Prediction of 90-Day All-Cause Mortality after Acute Ischemic Stroke-Results from the Linz Stroke Unit Study.

BACKGROUND: Early outcome prediction after acute ischemic stroke is of great interest. The aim of our study was to evaluate the prognostic value of blood biomarkers in patients with acute ischemic stroke. METHODS: We measured interleukin-6 (IL-6), d-dimer, amino-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T, and soluble ST2 plasma concentrations within 24 h after admission to our stroke unit in 721 consecutive acute ischemic stroke patients. End point was 90-day all-cause mortality. RESULTS: During follow-up 81 patients died (11%). In univariate Cox proportional hazards regression analyses with the biochemical markers dichotomized according to median values, all baseline blood biomarkers were strong prognostic markers. However, in the multivariate analysis after adjustment for several clinical variables and the NIH Stroke Scale (NIHSS), only NIHSS >3 [risk ratio (RR) 7.87, 95% CI, 3.61-17.16; P < 0.001], IL-6 > 7 pg/mL (RR 4.09, 95% CI, 2.02-8.29; P < 0.001), and NT-proBNP >447 ng/L (RR 4.88, 95% CI, 2.41-9.88; P < 0.001) remained independent predictors. Using a simple multimarker approach combining these 3 complementary markers, we demonstrated that patients with increased NIHSS, IL-6, and NT-proBNP had the poorest outcome with a mortality rate of 38%, whereas no patient with negative readings for all 3 markers died during follow-up. CONCLUSIONS: In this large cohort of patients with acute ischemic stroke, IL-6 and NT-proBNP at admission were strong and independent prognostic markers for 90-day all-cause mortality, and provided complementary prognostic information to the routinely used stroke severity score NIHSS.

Real-life experience with the specific reversal agent idarucizumab for the management of emergency situations in dabigatran-treated patients: a series of 11 cases.

Non-vitamin K antagonist oral anticoagulants (NOACs) have a favorable benefit-risk profile compared with vitamin K antagonists. However, the lack of specific reversal agents has made the management of some patients receiving long-term treatment with NOACs problematic in emergency situations such as major bleeding events or urgent procedures. Idarucizumab, a fully humanized Fab antibody fragment that binds specifically and with high affinity to dabigatran, was recently approved for use in adult patients treated with dabigatran when rapid reversal of its anticoagulant effect is required. Clinical experience with idarucizumab is currently limited. We report 11 real-life clinical cases in which idarucizumab was used after multidisciplinary consultation in a variety of emergency situations including severe postoperative bleeding, emergency high-bleeding-risk surgery (hip/spine surgery and neurosurgery), invasive diagnostic testing (lumbar puncture), intracranial bleeding (pre-pontine subarachnoid hemorrhage and lobar intracerebral hemorrhage) and thrombolysis with recombinant tissue plasminogen activator for acute ischemic stroke. This case series illustrates the role of idarucizumab in improving patient safety in rare emergency situations requiring rapid reversal of the anticoagulant effect of dabigatran, while highlighting the importance of information and education about the availability and appropriate use of this recently approved specific reversal agent.
