Abstract

Introduction: Cerebral venous sinus thrombosis associated with vaccine-induced immune thrombotic thrombocytopenia (CVST-VITT) is a severe disease with high mortality. There are few data on sex differences in CVST-VITT. The aim of our study was to investigate the differences in presentation, treatment, clinical course, complications, and outcome of CVST-VITT between women and men. Patients and methods: We used data from an ongoing international registry on CVST-VITT. VITT was diagnosed according to the Pavord criteria. We compared the characteristics of CVST-VITT in women and men. Results: Of 133 patients with possible, probable, or definite CVST-VITT, 102 (77%) were women. Women were slightly younger [median age 42 (IQR 28–54) vs 45 (28–56)], presented more often with coma (26% vs 10%) and had a lower platelet count at presentation [median (IQR) 50x109/L (28–79) vs 68 (30–125)] than men. The nadir platelet count was lower in women [median (IQR) 34 (19–62) vs 53 (20–92)]. More women received endovascular treatment than men (15% vs 6%). Rates of treatment with intravenous immunoglobulins were similar (63% vs 66%), as were new venous thromboembolic events (14% vs 14%) and major bleeding complications (30% vs 20%). Rates of good functional outcome (modified Rankin Scale 0-2, 42% vs 45%) and in-hospital death (39% vs 41%) did not differ. Discussion and conclusions: Three quarters of CVST-VITT patients in this study were women. Women were more severely affected at presentation, but clinical course and outcome did not differ between women and men. VITT-specific treatments were overall similar, but more women received endovascular treatment.

Abstract

Objective: Cerebral venous thrombosis (CVT) caused by vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare adverse effect of adenovirus-based severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) vaccines. In March 2021, after autoimmune pathogenesis of VITT was discovered, treatment recommendations were developed. These comprised immunomodulation, non-heparin anticoagulants, and avoidance of platelet transfusion. The aim of this study was to evaluate adherence to these recommendations and its association with mortality. Methods: We used data from an international prospective registry of patients with CVT after the adenovirus-based SARS-CoV-2 vaccination. We analyzed possible, probable, or definite VITT-CVT cases included until January 18, 2022. Immunomodulation entailed administration of intravenous immunoglobulins and/or plasmapheresis. Results: Ninety-nine patients with VITT-CVT from 71 hospitals in 17 countries were analyzed. Five of 38 (13%), 11 of 24 (46%), and 28 of 37 (76%) of the patients diagnosed in March, April, and from May onward, respectively, were treated in-line with VITT recommendations (p < 0.001). Overall, treatment according to recommendations had no statistically significant influence on mortality (14/44 [32%] vs 29/55 [52%], adjusted odds ratio [OR] = 0.43, 95% confidence interval [CI] = 0.16–1.19). However, patients who received immunomodulation had lower mortality (19/65 [29%] vs 24/34 [70%], adjusted OR = 0.19, 95% CI = 0.06–0.58). Treatment with non-heparin anticoagulants instead of heparins was not associated with lower mortality (17/51 [33%] vs 13/35 [37%], adjusted OR = 0.70, 95% CI = 0.24–2.04). Mortality was also not significantly influenced by platelet transfusion (17/27 [63%] vs 26/72 [36%], adjusted OR = 2.19, 95% CI = 0.74–6.54). Conclusions: In patients with VITT-CVT, adherence to VITT treatment recommendations improved over time. Immunomodulation seems crucial for reducing mortality of VITT-CVT., DEAL

Abstract

Importance: Thrombosis with thrombocytopenia syndrome (TTS) has been reported after vaccination with the SARS-CoV-2 vaccines ChAdOx1 nCov-19 (Oxford-AstraZeneca) and Ad26.COV2.S (Janssen/Johnson & Johnson). Objective: To describe the clinical characteristics and outcome of patients with cerebral venous sinus thrombosis (CVST) after SARS-CoV-2 vaccination with and without TTS. Design, Setting, and Participants: This cohort study used data from an international registry of consecutive patients with CVST within 28 days of SARS-CoV-2 vaccination included between March 29 and June 18, 2021, from 81 hospitals in 19 countries. For reference, data from patients with CVST between 2015 and 2018 were derived from an existing international registry. Clinical characteristics and mortality rate were described for adults with (1) CVST in the setting of SARS-CoV-2 vaccine-induced immune thrombotic thrombocytopenia, (2) CVST after SARS-CoV-2 vaccination not fulling criteria for TTS, and (3) CVST unrelated to SARS-CoV-2 vaccination. Exposures: Patients were classified as having TTS if they had new-onset thrombocytopenia without recent exposure to heparin, in accordance with the Brighton Collaboration interim criteria. Main Outcomes and Measures: Clinical characteristics and mortality rate. Results: Of 116 patients with postvaccination CVST, 78 (67.2%) had TTS, of whom 76 had been vaccinated with ChAdOx1 nCov-19; 38 (32.8%) had no indication of TTS. The control group included 207 patients with CVST before the COVID-19 pandemic. A total of 63 of 78 (81%), 30 of 38 (79%), and 145 of 207 (70.0%) patients, respectively, were female, and the mean (SD) age was 45 (14), 55 (20), and 42 (16) years, respectively. Concomitant thromboembolism occurred in 25 of 70 patients (36%) in the TTS group, 2 of 35 (6%) in the no TTS group, and 10 of 206 (4.9%) in the control group, and in-hospital mortality rates were 47% (36 of 76; 95% CI, 37-58), 5% (2 of 37; 95% CI, 1-18), and 3.9% (8 of 207; 95% CI

Abstract

Background and purposes: Stroke severity scales may expedite prehospital large vessel occlusion (LVO) stroke detection, but few are validated for paramedic use. We evaluated the feasibility of introducing the Cincinnati Stroke Triage Assessment Tool (C-STAT) in the field and its capacity to detect LVO stroke. Methods: We performed a prospective paramedic-based study assessing C-STAT in the field on patients currently redirected to two comprehensive stroke centers (CSC), based on a Cincinnati Prehospital Stroke Scale (CPSS) score of 3/3. C-STAT was administered by on-site paramedics with telephone guidance from trained centralized clinical support paramedics. Results: Between October 2018 and November 2019, C-STAT scores were obtained in 188/218 (86.2%) patients, among which 118/188 (62.8%) were positive. Paramedics reported performing the C-STAT in less than 5 minutes on 170/188 (90.4%) patients and noted no difficulties administering the scale in 151/188 (80.3%). A positive C-STAT identified 51/68 (75%) LVO strokes in the cohort, demonstrating a 43% (95% CI: 38%–48%) positive and 76% (95% CI: 66%–83%) negative predictive value for LVO stroke diagnosis. In a cohort of 100 patients with CPSS 3/3, requiring a positive C-STAT for redirection would decrease CSC patient volume by 37 but miss 9 of 36 LVO strokes. Conclusion: Prehospital administration of the C-STAT was feasible, using a model of minimal paramedic training and real-time telephone guidance. A protocol based on both a CPSS 3/3 and a positive C-STAT would decrease CSC redirected patient volume by one-third but would miss one-quarter of LVO strokes when compared to a CPSS-based protocol.

Abstract

La douleur articulaire associée à l’arthrose est un problème clinique majeur, spécialement chez les personnes âgées. L’intensité de la douleur est souvent amplifiée lors de mouvement de l’articulation et principalement lors du soutien de la charge corporelle sur le membre lésé. Malheureusement, les traitements pharmacologiques proposés sont trop souvent associés à des effets secondaires néfastes et à une inefficacité pour le soulagement de la douleur à long terme. Divers modèles murins sont utilisés en laboratoire de recherche pour des études précliniques de molécules aux propriétés analgésiques. Une évaluation comparative de la réponse comportementale douloureuse des animaux d’un modèle d’instabilité articulaire induit par le sectionnement du ligament croisé antérieur accompagné d’une méniscectomie partielle (le modèle ACLT+pMMx) et d’un modèle de dégénérescence articulaire induite par le monoiodoacetate (le modèle MIA) a permis de sélectionner un modèle approprié pour la continuité du projet. Les deux modèles ont démontré des lésions tissulaires, mais le modèle MIA a démontré une réponse douloureuse plus prononcée que le modèle ACLT+pMMx. Par l’analyse de la démarche, le modèle MIA a démontré une boiterie claire dans le patron de la démarche des animaux qui est associée à une lésion unilatérale. Le modèle MIA a donc été choisi pour la suite du projet. La problématique principale dans la recherche sur la douleur associée à l’arthrose est une compréhension incomplète des mécanismes de douleur responsables de l’induction et du maintien de l’état de douleur. Il devient donc nécessaire d’améliorer nos connaissances de ces mécanismes en effectuant une caractérisation plus approfondie des modèles animaux employés pour l’évaluation de stratégies pharmacologiques analgésiantes. Afin de bien comprendre le modèle MIA, une caractérisation des événements moléculaires centraux lors de la progression du processus dégénératif des structures articulaires de ce modèle s’est effectuée aux jours 3, 7, 14, 21 et 28 post injection. Des mécanismes hétérogènes qui modulent l’information nociceptive en fonction de la progression temporelle de la pathologie ont été observés. Les changements du contenu i spinal des neuropeptides sélectionnés (substance P, CGRP, dynorphine A et Big dynorphine) ont débuté sept jours suivant l’injection de MIA. L’observation histologique a démontré que les dommages structuraux les plus importants surviennent entre les jours 14 et 21. C’est entre les jours 7 et 21 que les lésions démontrent le plus de similarités à la pathologie humaine. Cela suggère que lors d’une évaluation préclinique d’un traitement pharmacologique pour pallier la douleur articulaire utilisant le modèle MIA, l’étude doit tenir compte de ces événements afin de maximiser l’évaluation de son efficacité. Puisque les traitements pharmacologiques conventionnels proposés pour le soulagement de la douleur ne font pas l’unanimité en terme d’efficacité, d’effets non désirés et de coûts monétaires parfois onéreux, les molécules de dérivés de plante deviennent une alternative intéressante. L’eugénol, le principal constituant de l’huile de clou de girofle, a été administré oralement pour une période de 28 jours chez des rats ayant reçu l’injection intra-articulaire de MIA afin d’évaluer son efficacité pour le traitement de la douleur articulaire. L’eugénol à une dose de 40 mg/kg s’est révélé efficace pour l’amélioration du patron de la démarche des animaux ainsi que pour la diminution de l’allodynie mécanique secondaire. De plus, les concentrations spinales de neuropeptides pronocicepteurs ont diminué chez les animaux traités. Par une évaluation histopathologique, l’eugénol n’a démontré aucune évidence d’effets toxiques suite à une administration per os quotidienne pour une période prolongée. Ces résultats suggèrent le potentiel thérapeutique complémentaire de la molécule d’eugénol pour le traitement de la douleur articulaire., Pain is the most predominant clinical symptom associated with osteoarthritis (OA), mostly among older people. Joint movement and weight bearing often increase the pain intensity. Unfortunately, the proposed pharmacological treatments are frequently associated with side effects and ineffective for pain alleviation for long time periods. Many murine models are used in laboratories for preclinical studies evaluating analgesic compounds. A comparative evaluation of the behavioral pain responses of animals with a joint instability model induced by the transection of the anterior cruciate ligament followed by a partial menisectomy (the ACLT+pMMx model) and of an articular degenerative model induced by an intra-articular injection of monoiodoacetate (the MIA model) was conducted to select an appropriate model for the continuation of the project. Both models demonstrated articular lésions, however the MIA model demonstrated a clearer behavioral pain response over the ACLT+pMMx model. The gait pattern of the MIA model revealed a clear limping gait similar to that observed with unilateral OA in humans. The MIA model was chosen for the subsequent studies. An unresolved issue in pain OA research is the lack of understanding of the pain mechanisms responsible for the induction and maintenance of the pain. Therefore, there is an urgent clinical need to improve the characterization of animal models to effectively discover novel pain relief pharmacological treatment stratégies for OA patients. A characterization of the spinal pain molecular events during the progression of the joint degenerative process in the MIA model was performed on days 3, 7, 14, 21 and 28 post injection. Heterogeneous nociceptive central molecular events were observed in respect to the time course of the pathology’s progression. Changes in selected spinal neuropeptide content (substance P, CGRP, dynorphin A, Big dynorphin) began 7 days following the MIA injection. Most severe joint structural damage on histology occured between days 14 and 21 post injection. These results suggest that preclinical drug evaluation employing this model should be conducted between 7 and 21 days post injection when the lesions resemble most those of human OA. iii As current pharmacological therapy for the alleviation of joint pain does not achieve the unanimity in respect to efficacy, side effects and cost, plant derivate compounds are now interesting alternatives to improve the situation. Eugenol, the main constituent of clove oil, was evaluated for its efficacy for alleviation of joint pain in rats who previously received an intra-articular injection of mono-iodoacetate to induce the MIA model. Eugenol, administered orally for 28 consecutive days at a dose of 40 mg/kg, improved gait pattern and reduced secondary mechanical allodynia. Furthermore, spinal concentrations of pronociceptive neuropeptides were also decreased in the treated animals. No toxic effects of the compoud were identified on histopathological assessment of the various tissues. These results suggest that eugenol could be a potential therapeutic option for alleviating OA joint pain.

Abstract

Background: Many stroke survivors experience arm and hand weakness, but there are only limited efficacious options for arm therapy available., Objective: To assess the feasibility of unsupervised home-based use of a virtual reality device (Smart Glove) for hand rehabilitation post stroke., Design: Prospective single-arm study consisting of a 2-week run-in phase with no device use followed by an 8-week intervention period., Setting: Participants were recruited at the Stanford Neuroscience Outpatient Clinic., Participants: Twenty chronic stroke patients with upper extremity impairment., Interventions: Participants were instructed to use the Smart Glove 50 minutes per day, 5 days per week for 8 weeks., Main Outcome Measures: The following outcomes were measured: (1) compliance, (2) patients' impression of the intervention, and (3) efficacy using the upper extremity Fugl-Meyer (UE-FM), the Jebsen-Taylor hand function test (JTHFT), and the Stroke Impact Scale (SIS)., Results: Of 20 participants, seven (35%) met target compliance of 40 days use, and six (30%) used the device for 20-39 days. Eighty-five percent of participants were satisfied with the therapy, with 80% reporting improvement in hand function. During the run-in phase there were no improvements in hand function. During the intervention, patients improved by a mean of 26.6 ± 48.8 seconds on the JTHFT (P = .03), by 16.1 ± 15.3 points on the hand-domain of the SIS (P < .01) and there was a trend toward improvement on the UE-FM (2.2 ± 5.5 points, P = .10)., Conclusions: Unsupervised use of the Smart Glove in the home environment may improve hand/arm function in subacute/chronic stroke patients. A randomized controlled trial is needed to confirm these results., (© 2021 American Academy of Physical Medicine and Rehabilitation.)

Abstract

Importance: Thrombosis with thrombocytopenia syndrome (TTS) has been reported after vaccination with the SARS-CoV-2 vaccines ChAdOx1 nCov-19 (Oxford-AstraZeneca) and Ad26.COV2.S (Janssen/Johnson & Johnson)., Objective: To describe the clinical characteristics and outcome of patients with cerebral venous sinus thrombosis (CVST) after SARS-CoV-2 vaccination with and without TTS., Design, Setting, and Participants: This cohort study used data from an international registry of consecutive patients with CVST within 28 days of SARS-CoV-2 vaccination included between March 29 and June 18, 2021, from 81 hospitals in 19 countries. For reference, data from patients with CVST between 2015 and 2018 were derived from an existing international registry. Clinical characteristics and mortality rate were described for adults with (1) CVST in the setting of SARS-CoV-2 vaccine-induced immune thrombotic thrombocytopenia, (2) CVST after SARS-CoV-2 vaccination not fulling criteria for TTS, and (3) CVST unrelated to SARS-CoV-2 vaccination., Exposures: Patients were classified as having TTS if they had new-onset thrombocytopenia without recent exposure to heparin, in accordance with the Brighton Collaboration interim criteria., Main Outcomes and Measures: Clinical characteristics and mortality rate., Results: Of 116 patients with postvaccination CVST, 78 (67.2%) had TTS, of whom 76 had been vaccinated with ChAdOx1 nCov-19; 38 (32.8%) had no indication of TTS. The control group included 207 patients with CVST before the COVID-19 pandemic. A total of 63 of 78 (81%), 30 of 38 (79%), and 145 of 207 (70.0%) patients, respectively, were female, and the mean (SD) age was 45 (14), 55 (20), and 42 (16) years, respectively. Concomitant thromboembolism occurred in 25 of 70 patients (36%) in the TTS group, 2 of 35 (6%) in the no TTS group, and 10 of 206 (4.9%) in the control group, and in-hospital mortality rates were 47% (36 of 76; 95% CI, 37-58), 5% (2 of 37; 95% CI, 1-18), and 3.9% (8 of 207; 95% CI, 2.0-7.4), respectively. The mortality rate was 61% (14 of 23) among patients in the TTS group diagnosed before the condition garnered attention in the scientific community and 42% (22 of 53) among patients diagnosed later., Conclusions and Relevance: In this cohort study of patients with CVST, a distinct clinical profile and high mortality rate was observed in patients meeting criteria for TTS after SARS-CoV-2 vaccination.

Abstract

In this paper, we propose symmetry measures for post stroke assessment based on gait signal profiles from inertial sensors. Ten healthy controls and eight post stroke patients performed 6-Minute Walk Tests while wearing an inertial sensor on top of each shoe. Symmetry measures based on the linear correlation and the normalized sample distance between left and right foot pitch angular velocity showed high discriminating power to differentiate post stroke gait from healthy controls (Cliff's D = 0.95, Wilcoxon test p<0.001). The proposed symmetry measures are simple to estimate and do not require spatiotemporal gait parameters while they provide comparable discriminating power than symmetry measures based on spatiotemporal gait characteristics such as maximum angular velocity and stance ratio of each cycle. The proposed symmetry measures have the potential for generalization in wearable sensor based gait symmetry assessment.
