Assessment of Mendelian and risk-factor genes in Alzheimer disease: A prospective nationwide clinical utility study and recommendations for genetic screening. Genet Med 2024; 26:101082. [PMID: 38281098 DOI: 10.1016/j.gim.2024.101082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 01/17/2024] [Accepted: 01/19/2024] [Indexed: 01/29/2024] Open
Abstract
PURPOSE To assess the likely pathogenic/pathogenic (LP/P) variants rates in Mendelian dementia genes and the moderate-to-strong risk factors rates in patients with Alzheimer disease (AD). METHODS We included 700 patients in a prospective study and performed exome sequencing. A panel of 28 Mendelian and 6 risk-factor genes was interpreted and returned to patients. We built a framework for risk variant interpretation and risk gradation and assessed the detection rates among early-onset AD (EOAD, age of onset (AOO) ≤65 years, n = 608) depending on AOO and pedigree structure and late-onset AD (66 < AOO < 75, n = 92). RESULTS Twenty-one patients carried a LP/P variant in a Mendelian gene (all with EOAD, 3.4%), 20 of 21 affected APP, PSEN1, or PSEN2. LP/P variant detection rates in EOAD ranged from 1.7% to 11.6% based on AOO and pedigree structure. Risk factors were found in 69.5% of the remaining 679 patients, including 83 (12.2%) being heterozygotes for rare risk variants, in decreasing order of frequency, in TREM2, ABCA7, ATP8B4, SORL1, and ABCA1, including 5 heterozygotes for multiple rare risk variants, suggesting non-monogenic inheritance, even in some autosomal-dominant-like pedigrees. CONCLUSION We suggest that genetic screening should be proposed to all EOAD patients and should no longer be prioritized based on pedigree structure.

Distribution of atrial cardiomyopathy markers and association with atrial fibrillation detected after ischaemic stroke in the SAFAS study. Stroke Vasc Neurol 2024; 9:165-173. [PMID: 37429637 PMCID: PMC11103154 DOI: 10.1136/svn-2023-002447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 06/27/2023] [Indexed: 07/12/2023] Open
Abstract
BACKGROUND Atrial cardiomyopathy (AC) is an emerging concept explaining the pathophysiology of cardioembolic strokes in absence of atrial fibrillation (AF). A definition based on the presence of electrical abnormality (P-wave terminal force in lead V1 (PTFV1) >5000 µV×ms), N-Terminal pro-B-type natriuretic peptide (NT pro BNP) >250 pg/mL and/or indexed left atrial diameter (LADI) >3 cm/m² is currently tested in the ARCADIA (AtRial Cardiopathy and Antithrombotic Drugs In prevention After cryptogenic stroke) trial. We set out to estimate the prevalence of AC as defined in the ARCADIA trial, its determinants and its association with AF detected after stroke (AFDAS). METHODS Stepwise screening for silent Atrial Fibrillation After Stroke (SAFAS) study prospectively included 240 ischaemic stroke patients. AC markers were complete for 192 of them and 9 were not included in this analysis because AF had been diagnosed on admission. RESULTS A total of 183 patients were analysed, of whom 57% (104 patients) met the AC criteria (79 NT-proBNP, 47 PTFV1, 4 LADI). In the multivariate logistic regression, C reactive protein >3 mg/L (OR (95% CI) 2.60 (1.30 to 5.21), p=0.007) and age (OR (95% CI) 1.07 (1.04 to 1.10), p<0.001) were found to be independently associated with AC. After 6 months of follow-up, AFDAS was detected in 33% of AC patients and in 14% of the remaining ones (p=0.003). However, AC was not independently associated with AFDAS, contrary to left atrial volume index (>34 mL/m2, OR 2.35 (CI 1.09 to 5.06) p=0029). CONCLUSION AC as defined in ARCADIA is mostly based on NT pro BNP elevation (76% of patients) and is associated with age and inflammation. Moreover, AC was not independently associated with AFDAS at follow-up. The ARCADIA trial, which compares aspirin to apixaban in patients with embolic strokes of undetermined source with AC markers and must, therefore be analysed in the light of these limitations. TRIAL REGISTRATION NUMBER NCT03570060.

Abstract
BACKGROUND Persistent foramen ovale (PFO) contributes to cryptogenic stroke and is associated with stroke recurrence, although the exact mechanism of ischemic events is not fully understood. Several biomarkers have been developed for the prediction of atrial fibrillation after stroke, but there are currently only limited data on their potential value for the diagnosis of PFO-related stroke. METHODS This study was a prospective single-center study that included all patients hospitalized between March 31, 2018, and January 18, 2020, in the stroke department of the Dijon University Hospital for ischemic stroke without obvious cause and without a history of atrial fibrillation. PFO was systematically screened by transthoracic echocardiography and images were reviewed by an independent cardiologist blinded from clinical data. PFO was defined according to the CLOSE trial criteria: PFO associated with interatrial septal aneurysm or significant interatrial shunt (> 30 microbubbles in the left atrium within three cardiac cycles after right atrial opacification). The potential association of PFO-related stroke with biomarkers of cardiac fibrosis and inflammation such as galectin-3, GDF-15, ST-2, osteoprotegerin and NT-proBNP was tested using multivariate backward stepwise logistic regression. RESULTS Of the 240 patients included in the SAFAS study, 229 had complete echocardiographic data, and 23 (10%) had PFO-related stroke. Patients with PFO-related stroke were significantly younger (58±14 vs. 69±14, P<0.001), had less frequent previous arterial hypertension (30 vs. 60%, P=0.008), and more frequent cerebellar territory involvement (26 vs. 9%, P=0.014) compared to the other patients. In addition, they had less frequently left atrial dilatation (left atrial index volume>34mL/m2 [9 vs. 35%, P=0.009]). After ROC curve analysis for definition of thresholds, PFO-related stroke patients more often had galectin-3<9.5ng/mL (59 vs. 27%, P=0.002), ST2<13380pg/ml (23 vs. 50%, P=0.007), GDF-15<1200ng/mL (59 vs. 27%, P=0.002), osteoprotegerin<1133pg/mL (82 vs. 58%, P=0.033) and NT-proBNP<300pg/mL (88 vs. 55%, P=0.009). After multivariate analysis, only galectin-3<9.5ng/mL (OR [95% CI] 3.4 [1.18; 9.8], P=0.024) and osteoprotegerin<1133pg/L (OR [95% CI] 5.0 [1.1; 22.9], P=0.038) were independently associated with PFO-related stroke. CONCLUSION Patients in whom cryptogenic stroke is attributed to a significant PFO have a specific clinical and biological phenotype. Low levels of galectin-3 and osteoprotegerin may help identify patients with PFO-related strokes.

Abstract
BACKGROUND The need for early diagnosis biomarkers in Alzheimer's disease (AD) is growing. Only few studies have reported gustatory dysfunctions in AD using subjective taste tests. OBJECTIVE The main purpose of the study was to explore gustatory functions using subjective taste tests and recordings of gustatory evoked potentials (GEPs) for sucrose solution in patients with minor or major cognitive impairment (CI) linked to AD, and to compare them with healthy controls. The secondary objective was to evaluate the relationships between GEPs and the results of cognitive assessments and fasting blood samples. METHODS A total of 45 subjects (15 healthy subjects, 15 minor CI patients, 15 major CI patients) were included to compare their gustatory functions and brain activity by recording GEPs in response to a sucrose stimulation. CI groups were combined in second analyses in order to keep a high power in the study. Correlations were made with cognitive scores and hormone levels (ghrelin, leptin, insulin, serotonin). RESULTS Increased P1 latencies and reduced N1 amplitudes were observed in minor or major patients compared to controls. GEPs were undetectable in 6 major and 4 minor CI patients. Thresholds for sucrose detection were significantly higher in the major CI group than in controls or the minor CI group. No correlation was found with hormone levels. CONCLUSIONS The cortical processing of sensory taste information seems to be altered in patients with minor or major CI linked to AD. This disturbance was identifiable with subjective taste tests only later, at the major CI stage.

Abstract
PURPOSE To evaluate primary patency at 12 months after endovascular therapies in hepatic artery stenosis. METHODS A retrospective review of all endovascular interventions for hepatic artery stenosis (HAS) after liver transplantation that occurred between June 2013 and November 2020 was performed at a single institution in France. Follow up occurred from 1 month to 4 years (median 15 months). The treatment consisted of dilation with a balloon or stent. We analyzed short-term (technical success and complications) and long-term outcomes (liver function, arterial patency, graft survival at 12 months (GS), and reintervention). We also compared percutaneous balloon angioplasty (PBA) with stent placement. PBA alone was used if < 30% residual stenosis of the hepatic artery was achieved. Stenting was performed if there was greater than 30% residual stenosis and in the case of complications (dissection or rupture). RESULTS A total of 18 stenoses were suspected on the basis of routine surveillance duplex ultrasound imaging (peak systolic velocity > 200 cm/s, systolic accelerating time > 10 ms and resistive index < 0.5), all of which were confirmed by angio CT, but only 17 were confirmed by angiography. Seventeen patients were included (14 males, mean age 57 years; and three females, mean age 58 years). Interventions were performed in 17 cases (95%) with PBA only (5/17), stent only (5/17) or both (4/17). Immediate technical success was 100%. Major complications occurred in 1 of 17 cases (5.8%), consisting of target vessel dissection. The analysis of the three (groups PBA only, stent only or both) showed the same procedural success (100%), GS (100%) and normal liver function after the procedures but different rates of complications (20% vs. 0% vs. 0%), arterial patency at 12 months (60% vs. 80% vs. 85%) (p = 0.4), early stenosis (40% vs. 80% vs. 0%) or late stenosis (60% vs. 20% vs. 100%) and requirement for reintervention (40% vs. 20% vs. 14%) (p = 0.56). CONCLUSION This study suggests that PBA, stent, or both procedures show the same primary patency at 12 months. It is probably not a definitive answer, but these treatments are safe and effective for extending graft survival in the context of graft shortages.

Abstract
INTRODUCTION Although several variants of Guillain-Barré syndrome (GBS) have been described, they are uncommon, and the atypical clinical presentation of patients makes the diagnosis challenging. This article reports a case of acute bulbar palsy plus (ABPp) syndrome. CASE REPORT A 18-year-old patient was admitted to our hospital because of difficulty swallowing, slurred speech, tingling of the extremities of the 4 limbs, and diplopia. He reported abdominal pain and diarrhea 2 weeks earlier. Physical examination showed a low-pitched voice, palsy elevation of the soft palate and complete palsy of the abduction of the left eye. Electromyography and cerebrospinal fluid examination were unremarkable, but Campylobacter jejuni serology was positive, and we found an isolated immunoglobulin G (IgG) anti-GT1a antibodies positivity. A diagnosis of ABPp was finally made, and the patient fully recovered early after receiving polyvalent immunoglobulins infusion. CONCLUSIONS ABPp is classified as subtype of GBS. The most frequent clinical signs of ABPp are ophthalmoplegia, facial palsy, and ataxia. IgG anti-GT1a and/or anti-GQ1b are positive in a majority of patients with ABPp; however, these antibodies are not specific and can found in other subtypes of GBS.

Multimodal Approach for the Prediction of Atrial Fibrillation Detected After Stroke: SAFAS Study. Front Cardiovasc Med 2022; 9:949213.

Abstract
BackgroundIntensive screening for atrial fibrillation (AF) has led to a better recognition of this cause in stroke patients. However, it is currently debated whether AF Detected After Stroke (AFDAS) has the same pathophysiology and embolic risk as prior-to-stroke AF. We thus aimed to systematically approach AFDAS using a multimodal approach combining clinical, imaging, biological and electrocardiographic markers.MethodsPatients without previously known AF admitted to the Dijon University Hospital (France) stroke unit for acute ischemic stroke were prospectively enrolled. The primary endpoint was the presence of AFDAS at 6 months, diagnosed through admission ECG, continuous electrocardiographic monitoring, long-term external Holter during the hospital stay, or implantable cardiac monitor if clinically indicated after discharge.ResultsOf the 240 included patients, 77 (32%) developed AFDAS. Compared with sinus rhythm patients, those developing AFDAS were older, more often women and less often active smokers. AFDAS patients had higher blood levels of NT-proBNP, osteoprotegerin, galectin-3, GDF-15 and ST2, as well as increased left atrial indexed volume and lower left ventricular ejection fraction. After multivariable analysis, galectin-3 ≧ 9 ng/ml [OR 3.10; 95% CI (1.03–9.254), p = 0.042], NT-proBNP ≧ 290 pg/ml [OR 3.950; 95% CI (1.754–8.892, p = 0.001], OPG ≥ 887 pg/ml [OR 2.338; 95% CI (1.015–5.620), p = 0.046) and LAVI ≥ 33.5 ml/m2 [OR 2.982; 95% CI (1.342–6.625), p = 0.007] were independently associated with AFDAS.ConclusionA multimodal approach combining imaging, electrocardiography and original biological markers resulted in good predictive models for AFDAS. These results also suggest that AFDAS is probably related to an underlying atrial cardiopathy.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT03570060].

Abstract
Intracerebral hemorrhage accounts for approximately 15% of the 115,000 strokes occurring each year in France. Although therapeutic strategies are more limited than for ischemic stroke, major points in the management of intracerebral hemorrhage can reduce short term morbidity and mortality by limiting the expansion of the hematoma and the occurrence of early complications, and long term patients' outcome by reducing the risk of recurrence. This article aims to update the key elements that contribute to improve of the prognosis of intracerebral hemorrhage patients.

Abstract
(1) Background: The limited availability of thrombectomy-capable stroke centres raises questions about pre-hospital triage of patients with suspected stroke (IS) due to large vessel occlusion (LVO). Aims: This study aimed to evaluate the diagnostic accuracy of clinical stroke severity scales available for LVO detection. (2) Methods: Patients with IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013–2017). Clinical signs and arterial imaging data were collected. LVO was defined as an occlusion site affecting the terminal intracranial internal carotid artery, the M1 segment of the middle cerebral artery (MCA), or the basilar artery (restricted definition). A wide definition of LVO also included the M2 segment of the MCA. For each of the 16 evaluated scales, a receiver operator characteristic (ROC) analysis was performed, and the c-statistic representing the area under the ROC curve was evaluated to assess discrimination for predicting LVO. (3) Results: 971 patients were registered, including 123 patients (12.7%) with an LVO according to the restricted definition. The c-statistic for LVO detection ranged between 0.66 and 0.80 according to the different scales, with a sensibility varying from 70% to 98% and a specificity from 33% to 86%. According to the wide definition of LVO (174 patients, 17.9%), the c-statistic was slightly lower, ranging between 0.64 and 0.79. The sensitivity was 59% to 93%, and the specificity was 34% to 89%. (4) Conclusion: The clinical scales failed to combine a high sensitivity and a high specificity to detect LVO. Further studies are needed to determine the best strategy for pre-hospital triage of IS patients.

Abstract
Ischemic stroke accounts for 80% of overall stroke, and is one of the leading causes of death, disability and dementia in worldwide. Management of patients with acute ischemic stroke dramatically improved over time with the implementation of intensive care stroke units, the development of acute recanalization strategies, the optimization of the management of post-stroke complications, and the prevention of early stroke recurrence. The objective of this article is to provide a general overview of the current management of patients with acute ischemic stroke aiming at improving post-stroke outcome.

Abstract
INTRODUCTION Stroke is associated with major consequences in terms of socioeconomic impact and lost disability-adjusted life in young victims, thus justifying a careful surveillance of epidemiological trends. This study aimed to assess changes in the incidence of ischemic stroke in young adults over a long period. METHODS All cases of first-ever ischemic stroke that occurred among adults aged 18-55 years were prospectively recorded using the population-based Dijon Stroke Registry, from 1985 to 2017. Sex-specific annual incidence rates were calculated and were presented according to 6 time periods. Incidence rate ratios (IRRs) were determined to assess sex differences in stroke incidence. RESULTS Over the whole study period, 4,451 patients suffered a first-ever ischemic stroke. Among these patients, 469 (10.5%) were young adults (median age: 46 years, IQR: 39-50; 53.9% men). Incidence rates rose from the study period 2003 to 2007 compared with previous periods and remained stable thereafter, both in men and women. Hence, incidence per 100,000 per year was globally 11.0 (95% CI: 9.4-12.7) before 2003 and 22.9 (20.3-25.6) thereafter. In individuals aged 18-45 years, incidence rates were 5.4 (4.3-6.9) overall, 4.1 (2.7-6.0) in men, and 6.7 (4.9-9.0) in women, before 2003. After 2003, incidence rates rose to 12.8 (10.7-15.1) overall, 12.0 (9.2-15.4) in men, and 13.6 (10.6-17.0) in women. In this age group, the men/women IRR was 0.78 (95% CI: 0.62-1.26, p = 0.08), although sex differences decreased over time (IRR = 0.62; 95% CI: 0.36-1.02, p = 0.046 before 2003, vs. IRR = 0.88; 95% CI: 0.62-1.26, p = 0.48 after 2003). In individuals aged 45-55 years, incidence rates before 2003 were 47 (37-61) in men and 25 (17-35) in women (IRR = 1.90; 95% CI: 1.24-2.97, p < 0.001), and they increased to 82 (67-100) in men and 46 (35-59) in women (IRR = 1.79; 95% CI: 1.29-2.49, p < 0.001) after 2003. CONCLUSIONS The incidence of ischemic stroke in young adults increased during the early 2000s and remained stable thereafter. These results highlight the priority need for dedicated prevention strategies for the young to reduce the burden of stroke.

Abstract
BACKGROUND the ongoing growing and ageing population is associated with an increase in older patients suffering a stroke. We aimed to assess the current profile of these patients in a population-based setting. METHODS all patients with acute stroke were prospectively identified among residents of Dijon, France, between 2013 and 2017, using a population-based registry. Characteristics and early outcome of patients were compared according to age groups. RESULTS 1,288 stroke cases were recorded (median age: 81.1 years, interquartile range: 66.1-86.7, 54% women). Patients aged 75-85 years and those >85 years accounted for 27.6 and 33.9% of overall cases. Increasing age was associated with a greater prevalence of vascular risk factors, pre-existing cognitive impairment and handicap, higher initial severity, more frequent cardioembolic ischemic stroke, post-stroke pulmonary infection and delirium. Only 41% of patients aged 75-85 years and 18% of those aged >85 years had a good early recovery. Compared with patients aged <75 years, patients aged 75-85 years [adjusted odds ratio (OR) = 2.61; 95% confidence interval (CI): 1.74-3.93, P < 0.001] and those aged >85 years (adjusted OR = 7.18; 95% CI: 4.58-11.3, P < 0.001) had an increased risk of poor post-stroke functional outcome. Among survivors, the proportion of patients discharged to home was 60% in age group <75 years, compared with 49% in patients aged 75-85 years and 29% in those aged >85 years. Thirty per cent of patients >85 years old required a long-term care institution. CONCLUSION the increasing burden of stroke in older people has major implications for future treatment strategies and need for dedicated care facilities.

The variegated scallop, Mimachlamys varia, undergoes alterations in several of its metabolic pathways under short-term zinc exposure. COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY D-GENOMICS & PROTEOMICS 2020; 37:100779. [PMID: 33360397 DOI: 10.1016/j.cbd.2020.100779] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 10/19/2020] [Accepted: 11/20/2020] [Indexed: 01/25/2023]
Abstract
The variegated scallop (Mimachlamys varia) is a filter feeder bivalve encountered in marine regions of the Atlantic coast. In particular, it is present in the La Rochelle marina (France), where it is used for the biomonitoring of marine pollution, due to its ability to strongly bioaccumulate pollutants. In this semi-closed environment, contamination generated by port activities leads to an accumulation of both organic and metal pollutants. Zinc is one of these pollutants, present at a dose of up to 150 μg.L-1. This study investigated the effects of 48 h zinc exposure upon the metabolic profiles of Mimachlamys varia using UHPLC/QToF (ultra-high performance liquid chromatography-quadrupole time-of-flight) tandem mass spectrometry metabolomics. After acclimation in mesocosms recreating in situ conditions, both controls and exposed with Zn2+ (150 μg.L-1) bivalves were dissected to recover the gills after 48 h and stored at -80 °C before metabolites extraction. UHPLC/QToF tandem mass spectrometry was performed to study metabolite composition of samples. Statistical analysis of results using multivariate techniques showed a good classification between control and exposed groups. Eleven identified metabolites were found to be down-modulated in exposed scallops. These variations could reflect potential zinc effects on several of the biological processes, such as energy metabolism, osmoregulation and defense against oxidative stress. Among the eleven metabolites highlighted, four were reported for the first time in an aquatic organism exposed to Zn. This study demonstrates once again the diversity of interactions between bivalves and metals and the complexity of the physiological response of marine bivalves to pollutants.

Abstract
Background and Purpose:
Because of several methodological limitations, previous studies focusing on the prevalence of large vessel occlusion in ischemic stroke (IS) patients provided conflicting results. We evaluated the incidence of IS with a visible arterial occlusion using a comprehensive population-based registry.
Methods:
Patients with acute IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013–2017). All arterial imaging exams were reviewed to assess arterial occlusion. Annual incidence rates of IS (first-ever and recurrent events) and IS with a visible occlusion were calculated.
Results:
One thousand sixty cases of IS were recorded (mean age: 76.0±15.8 years, 53.9% women). Information about arterial imaging was available in 971 (91.6%) of them, and only preexisting dementia was independently associated with having missing information (odds ratio=0.34 [95% CI, 0.18–0.65],
P
=0.001). Among these patients, 284 (29.2%) had a visible arterial occlusion. Occlusion site was the anterior circulation in 226 patients (23.3% of overall patients with available data) and the posterior circulation in 58 patients (6.0%). A proximal occlusion of the anterior circulation was observed in 167 patients (17.2%). The crude annual incidence rate of total IS per 100 000 was 138 (95% CI, 129–146). Corresponding standardized rates were 66 (95% CI, 50–82) to the World Health Organization and 141 (95% CI, 118–164) to the 2013 European populations. The crude annual incidence rate of IS with a visible arterial occlusion per 100 000 was 37 (95% CI, 33–41) and that of IS with a proximal occlusion of the anterior circulation was 22 (95% CI, 18–25). Corresponding standardized rates were 18 (95% CI, 10–26) and 10 (95% CI, 8–13) to the World Health Organization population, and 38 (95% CI, 26–50) and 23 (95% CI, 19–26) to the 2013 European population, respectively.
Conclusions:
These results will be helpful to plan the need for thrombectomy-capable stroke center resources.

Abstract
Background and Purpose—
The ongoing ageing population is associated with an increasing number of patients with stroke who have preexisting cognitive impairment. This study aimed to evaluate clinical severity in patients with ischemic stroke according to prestroke cognitive status.
Methods—
Patients with ischemic stroke were prospectively identified among residents of Dijon, France using a population-based registry (2013–2017). Prestroke cognitive status (no impairment, mild cognitive impairment [MCI], or dementia) was recorded, and severity at stroke onset was measured using the National Institutes of Health Stroke Scale (NIHSS) score. Association between prestroke cognitive status and severity was evaluated using ordinal regression analysis models in which the NIHSS score was considered as a categorical variable.
Results—
Among the 1048 patients (mean age, 76.3±15.2 years; 54.0% women), a greater severity was observed in those with MCI (n=132; median NIHSS: 6; interquartile range, 2–15), and those with dementia (n=164; median NIHSS: 7; interquartile range, 3–16), than in patients without cognitive impairment (n=752; median NIHSS: 3; interquartile range, 1–9). MCI (odds ratio [OR], 1.70 [95% CI, 1.21–2.38];
P
=0.002) and dementia (OR, 2.24 [95% CI, 1.65–3.04];
P
<0.001) were both associated with a greater severity at onset. The association was still observed after adjustment for clinical variables and proximal arterial occlusion (OR, 1.52 [95% CI, 1.02–2.28];
P
=0.04 for MCI; OR, 2.16 [95% CI, 1.45–3.22];
P
<0.001 dementia). Further adjustment for prestroke handicap slightly reduced the magnitude of the association (OR, 1.49 [95% CI, 0.98–2.25];
P
=0.06 for MCI, and OR, 1.98 [95% CI, 1.26–3.12];
P
=0.02 for dementia). The greater severity in patients with prestroke cognitive impairment was not specifically driven by a more severe impairment of either motor or language function.
Conclusions—
Patients with preexisting cognitive impairment suffered more severe ischemic stroke. This result could reflect a lower brain tolerance of acute ischemia. Further studies are needed to explore the underlying mechanisms that could be targeted from therapeutic perspectives focusing on neuroprotection.

Abstract
OBJECTIVE We assessed the association between pre-stroke cognitive status and 90-day case-fatality. METHODS Patients with ischemic stroke (IS) or spontaneous intracerebral hemorrhage (ICH) were prospectively identified among residents of Dijon, France, between 2013 and 2015, using a population-based registry. Association between pre-stroke cognitive status and case-fatality at 90 days was evaluated using Cox regression. RESULTS Seven hundred sixty-two patients were identified, and information about pre-stroke cognitive status was obtained for 716 (92.6%) of them, including 603 IS (84.2%) and 113 ICH (15.8%). Before stroke, 99 (13.8%) patients had mild cognitive impairment (MCI) and 98 (13.7%) had dementia. Patients with cognitive impairment were older, had a higher prevalence of several risk factors, more severe stroke, more frequent ICH, and less admission to stroke unit. Case-fatality rate at 90 days was 11.7% in patients without cognitive impairment, 32.3% in MCI patients, and 55.1% in patients with dementia. In multivariable analyses, pre-existing MCI (hazard ratio [HR] 2.22, 95% CI 1.21-4.05, p = 0.009) and dementia (HR 4.35, 95% CI 2.49-7.61, p < 0.001) were both associated with 90-day case-fatality. CONCLUSION Pre-stroke MCI and dementia were both associated with increased mortality. These associations were not fully explained by baseline characteristics, pre-stroke dependency, stroke severity or patient management, and underlying reasons need to be investigated.

Abstract
Background: Fatigue is a frequent symptom after stroke. We aimed to determine the association between fatigue and cognitive performance in patients with ischemic stroke who received acute revascularization therapy (IV thrombolysis and/or mechanical thrombectomy). Methods: Seventy patients were prospectively included in the stroke unit of the University Hospital of Dijon, France. A follow-up was performed at 6 months with clinical examination, fatigue assessment by the Fatigue Severity Scale (FSS), and a comprehensive neuropsychological evaluation. Patients with fatigue (FSS score >4) were compared with patients without fatigue. Neuropsychological factors associated with fatigue at 6 months were analyzed using multivariable logistic regression models. Results: Fatigue was reported by 34.3% of patients. Patients with fatigue were older, had more frequent residual handicap, depressive symptoms, and impaired quality of life. They had more frequently low score (<26) on the MoCA scale (79.2 vs. 47.8%, OR = 4.15; 95% CI: 1.32-13, p = 0.015), memory impairment (60 vs. 30.6%, OR = 3.41; 95% CI: 1.09-10.7, p = 0.035), and executive dysfunction (65 vs. 30.8%, OR = 4.18; 95% CI: 1.33-13.1, p = 0.014). In multivariable logistic regression analysis, only memory impairment was independently associated with fatigue (OR = 5.70; 95% CI: 1.09-29.6, p = 0.039). Further analyses restricted to non-depressed patients (n = 58, 84.1%) showed in multivariable models that a score < 26 on MoCA scale (OR 5.12; 95% CI: 1.00-26.2, p = 0.05), and a memory impairment (OR = 6.17; 95% CI: 1.06-35.9, p = 0.043) were associated with fatigue. There was also a non-significant trend toward an association between divided attention deficit and fatigue (OR = 6.79; 95% CI: 0.80-57.6, p = 0.079). Conclusion: The association between fatigue and subtle cognitive impairment including memory or attention deficits could be of interest in elaborating future interventional studies to evaluate the impact of therapeutic strategies, including cognitive rehabilitation, on fatigue.

Air pollution and stroke. A new modifiable risk factor is in the air. Rev Neurol (Paris) 2019; 175:619-624.

Abstract
Evidence from epidemiological studies has demonstrated that outdoor air pollution is now a well-known major problem of public health, mainly in low and middle income countries. Contrasting with myocardial infarction, there are few data on the association of air pollution and stroke. METHODS We propose a narrative literature review of the effects and the underlying biological mechanisms of short- and long-term exposure to air pollutants on stroke risk and mortality, using the following key-words: stroke, cerebrovascular events, ischemic and haemorrhage stroke, transient ischaemic attack, mortality, air pollution and air pollutants. RESULTS Twenty-one papers were selected. Air pollution, of which whose small particulate matter are the most toxic, contributes to about one-third of the global burden of stroke. We can identify vulnerable patients with classical neuro-vascular risk factors or a prior history of stroke or transient ischemic attack or persons living in low-income countries. Biological mechanisms of this new morbid association are discussed. CONCLUSION Air pollution should be recognized as a silent killer inducing stroke whose mortality rates remain elevated by its role as a new modifiable neurovascular risk factor, needing public health policies.

Abstract
The role of psychosocial factors (PSF) in increased risk of stroke is a novel public health challenge, but unclear definitions for PSF and the multiple stroke subtypes have led to inconsistent reports. A review of this issue is therefore warranted. METHODS Several databases were used for this narrative systematic review (Medline, Embase and Cochrane Library). Two independent reviewers evaluated articles from between 2001 and 2018 on the themes of PSF and stroke/transient ischemic attack (TIA). PSF criteria were job strain, psychological interpersonal and behavioral stress, and social deprivation. Ischemic and hemorrhagic stroke and TIA subtypes were also identified. RESULTS Forty-five cohorts, five case-control studies and two meta-analyses were included. Despite mixed results, PSF were associated with an increased risk of ischemic and hemorrhagic stroke in populations of all ages, and more predominantly in women. CONCLUSION This broad review shows that the presence of PSF is associated with an increased risk stroke and TIA. As such, PSF must figure in both public health policy and stroke prevention programs, similar to other established metabolic and environmental factors.

Abstract
BACKGROUND We aimed to evaluate the impact of the ageing population on temporal trends in burden of stroke and to provide projections for the coming years. METHODS Stroke cases (ischemic strokes, spontaneous intracerebral hemorrhages, or undetermined strokes) were prospectively identified between 1987 and 2015 in Dijon, France, using a population-based registry. Age-standardized incidence rates of first-ever and recurrent stroke were calculated, and their temporal trends were assessed using age- and sex-adjusted annual incidence rate ratios (RR). RESULTS The population of Dijon increased by 3.8% over time, with an increase by 28% in the number of residents aged ≥75 years. We recorded 5,899 strokes including 5,101 patients with a first-ever event. Incidence of first-ever stroke was stable both in people < 75 and ≥75 years old, but an increase in standardized incidence rates of total strokes was noted due to a rise in the incidence of recurrent stroke (from 4.7/100,000/year in 1987-1994 to 12.3/100,000/year in 2009-2015 in people < 75 years old, RR 1.036; p < 0.001; from 74/100,000/year in 1987-1994 to 200/100,000/year in 2009-2015 in people ≥75 years, RR 1.040; p < 0.001). The absolute number of first-ever strokes increased by 43%, and that of total stroke events rose by 58% over time, with a more pronounced increase in people ≥75 years old (+47 and +65% respectively). The annual number of patients who survived > 90 days after a first-ever stroke increased by 90%. According to demographic projections, the total number of strokes will increase by 55% (+65% patients ≥75 years, and +25% patients < 75 years) by 2,030 in Dijon. CONCLUSIONS Ageing and growth of the population led to a rise in the absolute number of strokes, especially in the elderly, that is expected to increase dramatically in the coming years. Improved stroke care was accompanied with an increase in stroke survivors that contributed to a rise in recurrent events. Urgent action is needed to meet this epidemiological challenge.

Abstract
Although visual function is thought to be preserved in patients with locked-in syndrome (LIS), enabling them to communicate through vertical or lateral eye movements or blinking of the upper eyelid, nothing is known about the actual visual function of patients with LIS. The goal of this study is to evaluate the visual function of patients with LIS which may enable better evaluation of the state of consciousness of these patients. Patients with LIS seen in a single neurovascular unit of a tertiary center between 1997 and 2013 were retrospectively reviewed. Each patient had a specialized neuro-ophthalmological evaluation under optimal environmental conditions (light, contrast, examination distance, head position, best ergonomic adaptation, and establishment of a means of communication with help from the patient's friends/family). Visual acuity, extraocular eye movements, confrontational visual field, slit lamp and fundus examination were performed. Thirteen patients (6M/7F) were included in this study. Mean visual acuity was 20/60. Oculomotor examination was abnormal in 77%. Forty-six percent of patients presented binocular diplopia mainly related to a VIth nerve palsy. One patient presented complete ophthalmoplegia. Forty-six percent of patients had nystagmus responsible for oscillopsia (oculopalatal tremor). An abnormal visual field was observed in 17% of patients, and abnormal pupillary light response leading to photophobia was present in 22% of patients. Keratitis or dry eye syndrome was present in most patients and was a major cause of pain and visual impairment. Our results suggest that the visual function is impaired in all patients with LIS. This impairment is multifactorial including mostly binocular diplopia or oscillopsia but also refractive errors, dry eye syndrome, keratitis or visual field defect. This altered visual function may alter the ability of the patient to interact with his environment and lead to underestimation of their state of consciousness. An ophthalmologic evaluation would allow for improvement of these patients' comfort, their ability to communicate, and the assessment of their state of consciousness.

Abstract
PURPOSE This study was designed to evaluate and compare the efficacy of early treatment of CRVO with either hemodilution by erythrocytopheresis or intravitreal (IVT) ranibizumab, or both. MATERIAL AND METHODS A multicentric prospective randomized study including patients with CRVO for less than 1 month was designed. Patients were randomized into 3 treatment groups: hemodilution (HD group), 3 monthly intravitreal injections of ranibizumab followed by PRN treatment (IVT group), or combined treatment (IVT+HD group). A monthly evaluation during a 6-month follow-up included best-corrected visual acuity (BCVA) and macular thickness measurements with OCT. Fluorescein angiography was performed at baseline, month 2 and month 6. Local and systemic tolerability of the different treatments were also compared. RESULTS Forty-four CRVO patients were included between February 2010 and June 2013: 20 in the IVT group, 13 in the HD group and 11 in the HD+IVT group. The mean duration of CRVO at baseline was 10 days and 16 days at the time of treatment without any significant difference between groups. Retinal ischemia was present at baseline in 40% of eyes in each group. After a 6-month follow-up, no difference between the 3 groups was observed in BCVA (10.5 ETDRS letters, 14.6 and 14.1 in the IVT group, HD group and IVT+HD group respectively, P=0.726) or in macular thickness (398 μ, 440 μ and 379 μ respectively, P=0.465). The time until treatment from CRVO onset, ranging from 1 to 35 days, was not correlated to final outcomes. No significant difference in the mean number of IVT (3.2 in the IVT+HD group vs 3.7 in the IVT group) was observed at 6 months. CONCLUSION No difference in BCVA nor in macular thickness was seen at M6 between the study groups. The duration of CRVO at the time of the initiation of the treatment was not correlated to better visual outcomes. Therefore, etiologic treatment with HD can still be proposed as a first-line treatment in young patients, which allows delaying or avoiding the IVT treatment and its potential side effects. Anti-VEGF IVT still remains an effective option in every case and can be started one month after the beginning of the CRVO.
