Frequency and predictors of decompressive craniectomy in ischemic stroke patients treated by mechanical thrombectomy in the ETIS registry.

BACKGROUND AND AIMS: Mechanical thrombectomy (MT) for patients with acute ischemic stroke (AIS) is usually performed in a comprehensive stroke center with on-site neurosurgical expertise. The question of whether MT can be performed in a primary stroke center without a neurosurgical facility is debated. In this context, there is a need to determine the frequency, delay and predictors of neurosurgical procedures in patients treated by MT. This study aims to determine these factors. METHODS: In total, 432 patients under 60years old, diagnosed with an acute ischemic stroke with a large vessel occlusion and treated by MT between January 2018 and December 2019 in six French stroke centers, were selected from the French clinical registry ETIS. Univariate and multivariate logistic regression models were used to identify predictive factors for decompressive craniectomy. RESULTS: Among the 432 included patients, 43 (9.9%) patients with an anterior circulation infarct underwent decompressive craniectomy. Higher admission NIHSS (OR: 1.08 [95% CI: 1.02-1.16]), lower ASPECT (OR per 1 point of decrease 1.53 [1.31-1.79] P<0.001) and preadmission antiplatelet use (OR: 3.03 [1.31-7.01]) were independent risk factors for decompressive craniectomy. The risk of decompressive craniectomy increases to more than 30% with an ASPECT score<4, an NIHSS>16, and current antiplatelet use. CONCLUSION: In this multicenter registry, 9% of acute ischemic stroke patients (<60years old) treated with MT, required decompressive craniectomy. Higher NIHSS score, lower ASPECT score, and preadmission antiplatelet use increase the risk of subsequent requirement for decompressive craniectomy.

TICI-RANKIN mismatch: Poor clinical outcome despite complete endovascular reperfusion in the ETIS Registry.

INTRODUCTION: Endovascular treatment (EVT) is a well-established technic for acute ischemic stroke, but despite a high recanalization rate of near 80%, at 3 months roughly 50% of patients have a poor functional outcome with a modified Rankin score (mRS) ≥3. The aim of this study was to determine predictive factors of poor functional outcomes in patients with complete recanalization after EVT, defined as modified thrombolysis in cerebral infarction (mTICI) 3. PATIENTS AND METHODS: This retrospective analysis based on the prospective multicenter ETIS registry (endovascular treatment in ischemic stroke) in France included 795 patients from January 2015 and November 2019 with acute ischemic stroke due to anterior circulation occlusion and prestroke mRS 0-1, treated with EVT and who achieved complete recanalization. Univariate and multivariate logistic regression models were used to identify predictive factors of poor functional outcome. RESULTS: 365 patients (46%) showed a poor functional outcome (mRS>2). In backward-stepwise logistic regression analysis, poor functional outcome was independently associated with older age (OR per 10-year increase, 1.51; 95%CI, 1.30 to 1.75), higher admission NIHSS (OR per 1 point increase, 1.28; 95%CI, 1.21 to 1.34), absence of prior intravenous thrombolysis (OR, 0.59; 95%CI, 0.39 to 0.90), and an unfavorable 24-hour NIHSS change (24h-baseline) (OR, 0.82; 95%CI, 0.79 to 0.87). We calculated that patients whose 24h NIHSS decreased by less than 5 points are more at risk of a poor outcome, with a sensitivity and a specificity of 65.0%. CONCLUSION: Despite complete reperfusion after EVT, half of patients had a poor clinical outcome. These patients, who were mainly older with a high initial NIHSS and an unfavorable post-EVT 24h NIHSS change, could represent a target population for early neurorepair and neurorestorative strategies.

[Evaluation of the success of medical abortion by a plasma hCG control threshold]. / Évaluation du succès de l'interruption volontaire de grossesse médicamenteuse par un seuil d'hCG sérique.

OBJECTIVES: In France, monitoring of the success of medical abortion is recommended 2 to 3 weeks after the procedure. However, there is no clear consensus on the modalities of this monitoring. The main objective of this study is to identify a threshold of serum hCG (human chorionic gonadotropin) control for medical abortions ≤7 weeks of gestation below which success can be confirmed without recourse to pelvic ultrasound. METHODS: This is a retrospective multicenter study conducted over a 14-month period. The serum hCG level, measured between the 15th and 25th day following the abortion, was compared with the results of the pelvic ultrasound performed at the follow-up visit. Ultrasound failure was defined as retention or persistent pregnancy. RESULTS: Among the 624 women included, the failure rate was 22.3%, including 86.3% of retentions, 8.6% of pregnancies stopped and 5% of pregnancies progressed. Using a ROC curve, the threshold value of hCG found to exclude failure at 95% was 253 IU/l (AUC=0.9202, sensitivity=84.17%, specificity=85.95% and positive predictive value [PPV]=63%). CONCLUSIONS: A serum hCG level ≤253 IU/l is sufficient to affirm the efficacy of medical abortion. However, since PPV is only 63% for this threshold, ultrasound should be reserved for women with high hCG levels.

Factors that predict a change in quality of life among Parkinson's disease patients participating in a patient education program.

BACKGROUND: Patient education is essential in Parkinson's disease (PD). However, it is not known which aspects of patient education are associated with an improvement in quality of life (QoL). OBJECTIVE: To identify factors that predicted an improvement in QoL in PD patients that participate in an education program. METHODS: EduPark is a community-hospital patient education program. PD Patients that had participated in the program between September 2013 and March 2017 were retrospectively included. QoL was prospectively evaluated (using the PDQ-8 questionnaire) before and after the patient's participation. We used mixed linear models (adjusted for the initial value of the PDQ-8) to determine socio-demographic and clinical variables that predicted the change in the PDQ-8 score. RESULTS: A total of 181 patients were included (mean±standard deviation age: 62.9±8.2 years; disease duration: 9.1±5.3 years). 76.7% of the 103 patients having undergone a cognitive evaluation did not display cognitive impairment. We did not identify any factors that predicted the program's impact on the patient's QoL. Participation in the program was associated with a significant decrease (improvement) in the PDQ-8 score (39.4±17.81 before and 35.6±15.9 afterwards, P<0.001). CONCLUSION: We did not identify any factors that were predictive of the patient education program's impact on QoL in patients with PD. Participation in the program was associated with a significant improvement in QoL. Our results suggest that Patient Education Programs should be more widely prescribed and developed in the management of PD.

TMJ related short-term outcomes comparing two different osteosynthesis techniques for bilateral sagittal split osteotomy.

OBJECTIVES: Bilateral sagittal split osteotomy (BSSO) is a morpho-functional surgery and post-surgical osteosynthesis may influence temporomandibular joint (TMJ) health. Our objective was to evaluate temporomandibular disorders (TMD) and TMJ symptoms after orthognathic surgery according to the type of osteosynthesis used in a population of patients with dentofacial deformities. MATERIALS AND METHODS: One hundred and eighty-three consecutive patients undergoing orthodontic and maxillofacial surgery treatment for correction of their malocclusion were recruited for a two-year period at Lille University Hospital. All patients had at least a mandibular BSSO using Epker's technique. Each patient was examined before and one year after orthognathic surgery. We compared osteosynthesis by miniplates fixed with monocortical screws (n=42) and the hybrid fixation with bicortical retro-molar screws used with miniplates (n=141). TMJ health was assessed by monitoring TMD signs and symptoms according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and scores obtained from the "Jaw Pain Function" questionnaire. RESULTS: There was no significant difference in pre-operative and one year post-operative RDC/TMD assessments (p≥0.91) or JPF score (p≥0.29) between the two types of osteosynthesis. CONCLUSION: There was no difference in TMJ health between the two techniques of osteosynthesis after BSSO. CLINICAL RELEVANCE: In our experience the hybrid technique fixation affords many advantages and does not influence postoperative TMD compared with osteosynthesis by miniplates.

Quality of life associated with orthotopic neobladder and ileal conduit in women: A multicentric cross-sectional study.

PURPOSE: To compare quality of life and functional outcomes associated with orthotopic neobladder (ONB) and ileal conduit (IC) after anterior pelvic exenteration for bladder cancer in women, through a multicentric cross-sectional study. METHODS: All women who have undergone an anterior pelvic exenteration associated with ONB or IC for a bladder cancer between January 2004 and December 2014 within the three participating university hospital centers and that were still alive in February 2016 were included. Three distinct auto-administered questionnaires were submitted to the patients: the EORTC QLQ-C30, the EORTC QLQ-BLmi30 and the SF-12. Comparison of response to these questionnaires between women with ONB and those with IC were studied with Mann-Whitney U tests, with a statistically significant P-value set at<0.05. The primary endpoint was the "global health status" sub-score extracted from the EORTC QLQ-C30 questionnaire. The secondary endpoints were the functional sub-scores and symptoms sub-scores obtained with the EORTC QLQ-C30 questionnaire as well as the sub-scores obtained with the EORTC QLQ-BLmi30 and the SF-12 questionnaires. RESULTS: Forty women were included in the study (17 ONB, 23 IC). The primary endpoint was comparable between the ONB and IC women (83.3 vs. 66.7 P=0.22). Similarly, no significant statistical difference could be pointed between the ONB and IC women in terms of secondary endpoints. CONCLUSION: The present study did not report any significance difference in terms of quality of life and functional outcomes between women with ONB and those with IC after pelvic exenteration for bladder cancer. LEVEL OF EVIDENCE: 3.

Long-term effects of pulmonary rehabilitation on daily life physical activity of patients with stage IV sarcoidosis: A randomized controlled trial.

INTRODUCTION: Pulmonary rehabilitation (PR) is known to improve exercise tolerance, mood, and quality of life in patients with chronic respiratory diseases. The aim of this work was to determine whether PR provides long-term benefits in increasing daily life physical activity in patients with chronic sarcoidosis. METHODS: This randomized prospective study (registered ClinicalTrials.gov NCT02044939) of 38 patients with stage IV chronic sarcoidosis was performed between 2012 and 2016. Patients were assigned to participate in a 2-month PR program (n=20) or receive counseling (n=18). Assessments were performed at baseline, 2 months (end of the PR program), 6months, and 12months, and included daily life physical activity parameters (measured for 5 consecutive days), exercise tolerance, dyspnea, anxiety, depression, fatigue, and quality of life. The primary outcome was the 12-month change in time spent in activities above an estimated energy expenditure of 2.5metabolic equivalents (METs). Secondary daily life physical activity outcomes included number of steps per day, total daily energy expenditure, and total energy expenditure above 2.5METs. RESULTS: The primary outcome did not differ between the two groups; mean between-group differences were -13.2min (95% confidence interval [CI]: -76.3 to 49.8) at 6 months and -18.1min (95% CI: -55.7 to 19.4) at 12months. Although PR had no effect on secondary daily life physical activity outcomes, it did significantly increase exercise tolerance at 6 and 12 months and decrease the dyspnea score at 6 months and the fatigue score at 12months. CONCLUSION: This trial failed to demonstrate a beneficial effect of PR on daily life physical activity in sarcoidosis patients, suggesting that long-term behavioral programs may be necessary to complement PR.

Safety and effectiveness of levodopa-carbidopa intestinal gel for advanced Parkinson's disease: A large single-center study.

BACKGROUND: Treatment with levodopa-carbidopa intestinal gel (LCIG) can effectively relieve motor and non-motor symptoms in advanced Parkinson's disease (PD). However, adverse events (AEs) are frequent. OBJECTIVE: To describe AEs associated with LCIG treatment and the main reasons for treatment discontinuation. We also looked for factors that were potentially predictive of serious AEs and assessed the effectiveness of and satisfaction with LCIG. METHOD: We retrospectively analyzed data on AEs in patients treated with LCIG at a French university medical center. For patients still receiving treatment at last follow-up, effectiveness was assessed according to the Clinical Global Impression (CGI) scale and the Movement Disorders Society - Unified Parkinson's Disease Rating Scale motor score. RESULTS: Of the 63 patients treated with LCIG for a mean (range) of 19 months (8-47), 57 (90%) experienced at least one AE (340 AEs in total). Most of the AEs (in 69.8% of the patients) were related to percutaneous endoscopic gastrostomy with a jejunal tube (PEG-J) or affected the gastrointestinal tract (granuloma, leakage, or a local infection). Device-related AEs (such as PEG-J removal and device occlusion) were frequent (in 63.5% of patients). Forty-three patients (68%) required at least one additional endoscopic procedure. Dopatherapy-related AEs occurred in 30 patients (48%). Most of the AEs occurred long after treatment initiations, and only a small proportion led to discontinuation. On the CGI scale, 53 patients (84.4%) considered that their condition had improved during LCIG treatment. CONCLUSION: Despite the high frequency of AEs, patients with advanced PD gain clinical benefit from treatment with LCIG. This treatment requires a competent, multidisciplinary team on site.

First-Line Sofia Aspiration Thrombectomy Approach within the Endovascular Treatment of Ischemic Stroke Multicentric Registry: Efficacy, Safety, and Predictive Factors of Success.

BACKGROUND AND PURPOSE: After publications on the effectiveness of mechanical thrombectomy by stent retrievers in acute ischemic stroke with large-vessel occlusion, alternative endovascular approaches have been proposed using first-line aspiration catheters. Several devices are currently available to perform A Direct Aspiration First Pass Technique. The Sofia catheter aspiration has been widely used by interventionalists, but data are scarce about its efficacy and safety. Our aim was to report our multicenter thrombectomy experience with first-line Sofia catheter aspiration and to identify independent prognostic factors of clinical and procedural outcomes. MATERIALS AND METHODS: We performed a retrospective analysis of the prospectively maintained Endovascular Treatment of Ischemic Stroke multicentric registry. Data from consecutive patients who benefited from thrombectomy with a first-line Sofia approach between January 2013 and April 2018 were studied. We excluded other first-line approaches (stent retriever or combined aspiration and stent retriever) and extracranial occlusions. Baseline characteristics, procedural data, and angiographic and clinical outcomes were analyzed. RESULTS: During the study period, 296 patients were treated. Mean age and initial NIHSS score were, respectively, 69.5 years and 16. Successful reperfusion, defined by the modified TICI 2b/3, was obtained in 86.1% (n = 255; 95% CI, 81.7%-89.9%). Complete reperfusion (modified TICI 3) was obtained in 41.2% (n = 122; 95% CI, 35.5%-47.1%). A first-pass effect was achieved in 24.2% (n = 71; 95% CI, 19.4%-29.6%). A rescue stent retriever approach was required in 29.7% (n = 88; 95% CI, 24.6%-35.3%). The complication rate was 9.5% (n = 28; 95% CI, 6.4%-13.5%). Forty-three percent (n = 122; 95% CI, 37.1%-48.9%) of patients presented with a favorable 3-month outcome (mRS ≤ 2). Older age, M1-occlusion topography, and intravenous thrombolysis use prior to thrombectomy were independent predictors of the first-pass effect. CONCLUSIONS: The first-line contact aspiration approach appeared safe and efficient with Sofia catheters. These devices achieved very high reperfusion rates with a low requirement for stent retriever rescue therapy, especially for M1 occlusions.

[Cervical ripening and labor induction: Evaluation of single balloon catheter compared to double balloon catheter and dinoprostone insert]. / Méthodes de maturation cervicale et déclenchement du travail : évaluation de la sonde simple ballonnet comparée à la sonde double ballonnet et aux prostaglandines.

OBJECTIVE: To compare the effectiveness of single balloon catheter with double balloon catheter and dinoprostone insert for cervical ripening and labor induction on unfavourable cervix. METHODS: this is a comparative, retrospective, one-center trial. Were included singleton pregnancy in cephalic presentation. Were excluded cicatricial uterus. The outcomes were vaginal delivery rate, caesarean section rate, modification in Bishop score, time from induction to delivery, second time prostaglandin E2 resort, oxytocin administration resort, maternal or neonatal adverse events. RESULTS: Were included 108 patients: 45 in single balloon catheter group, 32 in double balloon catheter group, 31 in dinoprostone insert group. Vaginal delivery rate was similar in single balloon catheter group (78 %) compared with others groups (75 % in double balloon catheter and 71 % in dinoprostone insert group respectively). Oxytocin administration resort was superior in single balloon catheter group. There was no significant difference on others outcomes. Labor induction costs were 9euros in single balloon catheter group, versus 55 and 81 euros in double balloon catheter group and dinoprostone insert group respectively. CONCLUSIONS: Single balloon catheter seems just as effective as double balloon catheter and dinoprostone insert with its major asset the low cost for labor induction.

Impact of intravenous thrombolysis and emergent carotid stenting on reperfusion and clinical outcomes in patients with acute stroke with tandem lesion treated with thrombectomy: a collaborative pooled analysis.

BACKGROUND AND PURPOSE: Tandem anterior circulation lesions in the setting of acute ischemic stroke (AIS) are a complex endovascular situation that has not been specifically addressed in trials. We determined the predictors of successful reperfusion and good clinical outcome at 90 days after mechanical thrombectomy (MT) in patients with AIS with tandem lesions in a pooled collaborative study. METHODS: This was a retrospective analysis of consecutive patients presenting to 18 comprehensive stroke centers with AIS due to tandem lesion of the anterior circulation who underwent MT. RESULTS: A total of 395 patients were included. Successful reperfusion (modified thrombolysis in cerebral infarction score 2b-3) was achieved in 76.7%. At 90 days, 52.2% achieved a good outcome (modified Rankin Scale score 0-2), 13.8% suffered a parenchymal hematoma and 13.2% were dead. Lower National Institutes of Health Stroke Scale score [odds ratio (OR), 1.26; 95% confidence intervals (CI), 1.07-1.48, P = 0.004], Alberta Stroke Program Early CT Score ≥7 (OR, 2.00; 95% CI, 1.07-3.43, P = 0.011), intravenous thrombolysis (OR, 1.47; 95% CI, 1.01-2.12, P = 0.042) and stenting of the extracranial carotid lesion (OR, 1.63; 95% CI, 1.04-2;53, P = 0.030) were independently associated with successful reperfusion. Lower age (OR, 1.58; 95% CI, 1.26-1.97, P < 0.001), absence of hypercholesterolemia (OR, 1.77; 95% CI, 1.10-2.84, P = 0.018), lower National Institutes of Health Stroke Scale scores (OR, 2.04; 95% CI, 1.53-2.72, P < 0.001), Alberta Stroke Program Early CT Score ≥7 (OR, 2.75; 95% CI, 1.24-6.10, P = 0.013) and proximal middle cerebral artery occlusion (OR, 1.59; 95% CI, 1.03-2.44, P = 0.035) independently predicted a good 90-day outcome. CONCLUSIONS: Intravenous thrombolysis and emergent stenting of the extracranial carotid lesion were predictors of a successful reperfusion after MT of patients with AIS with tandem lesion of the anterior circulation.

Unknown-onset strokes with anterior circulation occlusion treated by thrombectomy after DWI-FLAIR mismatch selection.

BACKGROUND AND PURPOSE: The DAWN trial recently showed compelling evidence in treating late window and wake-up stroke patients with thrombectomy using a clinical-imaging mismatch. The aim was to evaluate the results of thrombectomy for unknown-onset strokes (UOS) treated in our centres after a diffusion weighted imaging/fluid attenuated inversion recovery (DWI-FLAIR) mismatch based selection. METHODS: A multicentre, cohort study was performed of consecutive UOS treated by thrombectomy between 2012 and 2016. UOS with proximal anterior circulation occlusion discovered beyond 6 h from 'last seen normal' were compared with known-onset strokes (KOS) for whom thrombectomy was started within 6 h from onset. Time intervals were recorded from first time found abnormal. Results were adjusted for age, diabetes, hypertension, National Institutes of Health Stroke Scale, site of occlusion, DWI Alberta Stroke Programme Early CT Score, intravenous thrombolysis and use of general anaesthesia. RESULTS: Amongst 1246 strokes with anterior circulation occlusion treated by thrombectomy, 277 were UOS, with a 'last time seen well' beyond 6 h and DWI-FLAIR mismatch, and 865 were KOS who underwent groin puncture within 6 h. Favourable outcome was achieved less often in UOS than KOS patients (45.2% vs. 53.9%, P = 0.022). After pre-specified adjustment, this difference was not significant (adjusted relative risk 0.91; 95% confidence interval 0.80-1.04; P = 0.17). No differences were found in secondary outcomes. Time intervals from first found abnormal were significantly longer in UOS. CONCLUSION: Thrombectomy of UOS with anterior circulation occlusion and DWI-FLAIR mismatch appears to be as safe and efficient as thrombectomy of KOS within 6 h from onset. This pattern of imaging could be used for patient selection when time of onset is unknown.

MRI of the cervical spinal cord predicts respiratory dysfunction in ALS.

For patients with amyotrophic lateral sclerosis (ALS), the primary therapeutic goal is to minimize morbidity. Non-invasive ventilation improves survival. We aim to assess whether Magnetic Resonance Imaging (MRI) of the cervical spinal cord predicts the progression of respiratory disorders in ALS. Brain and spinal MRI was repeatedly performed in the SOD1G86R mouse model, in 40 patients and in healthy controls. Atrophy, iron overload, white matter diffusivity and neuronal loss were assessed. In Superoxide Dismutase-1 (SOD1) mice, iron accumulation appeared in the cervical spinal cord at symptom onset but disappeared with disease progression (after the onset of atrophy). In ALS patients, the volumes of the motor cortex and the medulla oblongata were already abnormally low at the time of diagnosis. Baseline diffusivity in the internal capsule was predictive of functional handicap. The decrease in cervical spinal cord volume from diagnosis to 3 months was predictive of the change in slow vital capacity at 12 months. MRI revealed marked abnormalities at the time of ALS diagnosis. Early atrophy of the cervical spinal cord may predict the progression of respiratory disorders, and so may be of value in patient care and as a primary endpoint in pilot neuroprotection studies.
