RESUMO
INTRODUCTION: Endovascular treatment (EVT) improves outcomes for basilar artery occlusion (BAO) with moderate-to-severe symptoms. However, the best treatment for mild symptoms (NIHSS score 0-10 and 0-5) remains unclear. This study compared EVT ± IVT to IVT alone in BAO patients with mild symptoms. PATIENTS AND METHODS: From the SITS-International Stroke Treatment Register, we included BAO patients with available baseline NIHSS score, treated by EVT, IVT, or both within 6 h of symptom onset from 2013 to 2021. Using the Doubly Robust approach (propensity score matching plus multivariable logistic regression), we analyzed efficacy (3-month mRS) and safety (SICH and 3-month death) outcomes for EVT ± IVT versus IVT alone in BAO patients with NIHSS scores 0-10 and 0-5. RESULTS: 1426 patients were included. For NIHSS scores 0-10 (180 matched, 1:1 ratio), outcomes were similar between EVT ± IVT and IVT alone groups. For NIHSS scores 0-5 (89 matched, 1:1 ratio), EVT ± IVT was associated with worse outcomes compared to IVT alone (mRS 0-2, aOR 0.20 [95% CI 0.06-0.61]; p = 0.005; mRS 0-3, aOR 0.27 [95% CI 0.08-0.89]; p = 0.031), but safety outcomes were similar. DISCUSSION: In early-treated BAO patients with mild symptoms, defined as NIHSS 0-10, there were no significant differences in outcomes between EVT ± IVT and IVT alone. However, for very mild symptoms, defined as NIHSS 0-5, IVT alone was associated with better outcomes compared to EVT ± IVT.Conclusion: Randomized trials are crucial to determine the optimal reperfusion therapy for BAO patients with mild symptoms.
RESUMO
BACKGROUND: Few certainties exist regarding optimal management of Blood Pressure (BP) in the very first hours after an ischemic stroke and many questions remain still unanswered. Our work aimed to evaluate the role of BP and its trend as possible determinants of in-hospital mortality (primary outcome), discharge disabilities and hospitalization length (secondary outcomes) in ischemic stroke patients presented with Hypertensive Emergencies (HE). METHODS: We retrospectively evaluated patients presented to Niguarda Hospital, Emergency Department (ED), from 2015 to 2017 with a neurological ischemic HE. BP at ED presentation (T0), its management in ED (T1) and its values at the stroke unit admission (T2) were evaluated. RESULTS: 267 patients were included (0.13 % of all ED accesses and 17.9 % of all ischemic strokes). In the whole population, BP values were not associated with in-hospital mortality while T0 and T2 SBP result were associated to discharge disability and hospitalization length. In pre-specified subgroup analysis these associations were confirmed only in untreated subjects (not anti-hypertensive nor thrombolysis). In fact, no significant relationship can be found between BP values and any secondary outcome in thrombolysis and anti-hypertensive treated patients. CONCLUSIONS: BP values and its management can not be related to in-hospital mortality in stroke patients, presented with HE, while they are associated to discharge disability and hospitalization length. In subgroup analysis, results were confirmed only in untreated (not anti-hypertensive therapies nor thrombolytic).

BACKGROUND: Intraluminal non-occlusive thrombus (ILT) is a rare cause of ischemic stroke. Although in most cases ILT is associated with arterial wall disorders, it has also been documented in patients with thrombophilic conditions. CASE REPORT: We present a case of carotid ILT in a 38-year-old puerperal woman with pregnancy-induced hypercoagulability. Following in vitro fertilization pregnancy, she experienced acute left-sided weakness 9 days after delivery. CT angiography revealed an intraluminal filling defect in the right carotid bulb, suggestive of a thrombus, along with ipsilateral MCA sub-occlusion. Mechanical thrombectomy was performed, achieving complete vessel recanalization without any endovascular intervention on the carotid ILT. Comprehensive evaluation excluded any underlying carotid vessel wall disease (such as atherosclerosis, inflammatory diseases, arterial dissection, focal dysplasia), inherited or acquired thrombophilia, and the sole prothrombotic risk factor identified was the puerperium. Histological thrombus analysis showed fibrin/platelet-rich material with significant macrophage infiltration (consistent with an intermediate/organized thrombus, suggesting potential embolization from a pre-existing carotid ILT). Anti-thrombotic treatment (acetylsalicylic acid 100 mg and enoxaparin 6000 UI) resulted in complete thrombus resolution at follow-up. CONCLUSION: ILT should be considered a potential case of embolic stroke in pregnancy or puerperium. Vessel imaging is essential for diagnosis. Histological thrombus analysis can provide insights into the pathophysiological mechanisms of stroke.

BACKGROUND: Endovascular thrombectomy (EVT) is a treatment option in patients with a cerebral venous thrombosis (CVT) who deteriorate despite anticoagulant treatment. Assessment of thrombus composition in CVT may provide insights into the pathophysiology of the disease and suggest new therapeutic strategies. CASE REPORT: A 47-year-old woman (smoking habit and estradiol/progesterone-releasing intra-uterine device) diagnosed with massive CVT underwent EVT (complete recanalization via aspiration catheter and stentriever) due to acute-onset left-sided weakness and dysarthria despite 72 h of full-dose subcutaneous low-molecular heparin. Two main reddish clots (maximum diameter 15 mm) were retrieved. Microscopic assessment showed an erythrocyte-rich thrombus (83.9% of entire thrombus surface) with layers of platelets/fibrin (lines of Zahn: 13.9% fibrin and 38.5% platelet [CD61+]). The immunological profile was dominated by neutrophils (30% MPO+), with neutrophil extracellular traps (NETs) in 1.9% of thrombus surface. T- (CD3+), B-lymphocytes (CD20+), and monocytes/macrophages (CD68+) were rather rare (2.2%, 0.7%, and 2.0% respectively). We found no evidence (0.0%) of hemosiderin and endothelial cells (CD34+). Full clinical recovery occurred prior to discharge. CONCLUSION: This is the first case report of a CVT with histologic assessment of the thrombus retrieved via EVT. Evaluating thrombi in CVT can provide key insights into disease pathophysiology and guide treatment advancements.

BACKGROUND: Medium-vessel occlusions (MeVO) are emerging as a new target for endovascular treatment (EVT). Primary MeVO occur de novo, while secondary MeVO arise from large vessel occlusion (LVO) through clot migration or fragmentation - spontaneously, following intravenous thrombolysis or EVT. We aimed to evaluate efficacy and safety of EVT in primary and EVT-induced secondary MeVO. METHODS: Retrospective single-center study on consecutive EVT-treated acute ischemic stroke, from 2019-to-2021. We considered: (1) exclusive-LVO, patients with LVO and - in case of residual distal occlusion - no rescue endovascular procedure; (2) primary MeVO: initial A2, A3, M2 non-dominant, M3, P2, P3 occlusions; (3) EVT-induced secondary MeVO, presenting LVO with subsequent (treated) EVT-induced MeVO. We compared (univariable/multivariable logistic regression) EVT efficacy (eTICI≥2b, 3-month modified Rankin Scale [mRS] 0-2) and safety (EVT-complications [vessel dissection, perforation, persistent-SAH], symptomatic ICH) in all MeVO versus exclusive-LVO, primary MeVO versus exclusive-LVO, EVT-induced secondary MeVO versus exclusive-LVO and EVT-induced secondary MeVO versus primary MeVO. RESULTS: We included 335 patients: 221 (66.0 %) exclusive-LVO and 114 (34.0 %) MeVO (55 [48.2 %] primary, 59 [51.8 %] secondary). Compared to exclusive-LVO, primary MeVO had higher rates of EVT complications (aOR 3.77 [95%CI 1.58-9.00],p=0.003), lower rates of eTICI≥2b (aOR 0.32 [95%CI 0.12-0.88],p=0.027) and mRS 0-2 (aOR 0.28 [95%CI 0.13-0.63],p=0.002). EVT-induced secondary MeVO had no major differences in efficacy and safety outcomes compared to exclusive-LVO, but a better mRS 0-2 (aOR 8.00 [95%CI 2.12-30.17],p=0.002) compared to primary MeVO. CONCLUSIONS: Primary and EVT-induced secondary MeVO showed different safety/efficacy EVT-related profiles. Dedicated randomized data are needed to identify the best acute reperfusion strategy in the two categories.

BACKGROUND: B-cell-depleting treatments, such as ocrelizumab and rituximab (anti-CD20), reduce humoral response to SARS-CoV-2 in people with Multiple Sclerosis (pwMS) and Neuromyelitis Optica Spectrum Disorder (NMOSD) and are associated with an increased risk of a more severe course of COVID-19 disease. The combination of tixagevimab and cilgavimab was authorized for COVID-19 prevention in immunocompromised subjects at high risk of severe COVID-19 disease, including patients treated with anti-CD20. Few real-world studies are available regarding the use of tixagevimab/cilgavimab in pwMS/NMOSD. In the present study, we describe the use of tixagevimab/cilgavimab for SARS-CoV-2 pre-exposure prophylaxis in a cohort of pwMS and NMOSD, treated with ocrelizumab and rituximab respectively. METHODS: 26 subjects were treated with tixagevimab/cilgavimab, while we used 18 patients as the control group. We collected clinical data at baseline in all patients and during scheduled follow up evaluations. SARS-CoV-2 serological status pre- and post-tixagevimab/cilgavimab treatment was available for 10 patients. RESULTS: We observed no adverse events following tixagevimab/cilgavimab treatment. Post-tixagevimab/cilgavimab anti-Spike-1-RBD IgG were significantly higher when compared to baseline values. No difference was found when comparing the percentage of COVID-19 infections between groups. All patients infected with SARS-CoV-2 had mild disease which did not require hospitalization. In patients treated with tixagevimab/cilgavimab, the rate of infection among patients exposed to SARS-CoV-2 was lower, without reaching statistical significance. We observed a significantly longer negativization time in the treated group. CONCLUSIONS: Our results are not consistent with what was observed in the registration trial and some more recent studies. We did not observe a difference in COVID-19 incidence nor in disease severity in MS and NMOSD between treated and untreated patients. Our different results may be partially explained by the change in SARS-CoV-2 variants epidemiology (i.e. reduced efficacy of tixagevimab and cilgavimab against the currently dominant variants) as well as different patient selection included in the trial and different dose of tixagevimab/cilgavimab used in other studies. The present report provides a real-life experience with tixagevimab/cilgavimab in pwMS and NMOSD treated with anti-CD20, with findings that are in line with the current SARS-CoV-2 epidemiology and the recent evidence regarding SARS-CoV-2 variants. Our results warrant further research to best treat patients in the present and future pandemic scenario.

Cerebral venous thrombosis (CVT) is a rare cause of stroke that tends to affect young people. Endovascular treatment (EVT) has not yet shown to be beneficial in CVT and is therefore actually only indicated as rescue therapy in severe and refractory cases for medical treatment. Clinical, neuroimaging, procedural and follow-up data were evaluated in order to define the safety and efficacy of EVT in the management of CVT between January 2016 and December 2022. Safety was assessed on the basis of recording adverse events. Functional outcomes (NIHSS, mRS) and neuroimaging were recorded at onset, at discharge and at a 6-month follow-up. Efficacy was assessed evaluating the recanalization rate at the end of the procedure. Twenty-one patients (17 female, 4 male, range 16-84 years) with CVT underwent EVT. Overall morbidity and mortality were both at 4.7%. Median NIHSS at the onset and at the discharge were, respectively, 10 and 2. Successful recanalization was achieved in 21/23 procedures (91.3%). Imaging follow-up (FUP) showed stable recanalization in all but one patient with successful recanalization. In 18/21 patients, a good clinical independence (mRS 0-2) was recorded at 6 months. Our study adds evidence on the safety and efficacy of endovascular techniques in the treatment of CVT.
RESUMO
COVID-19 may induce short- and long-term cognitive failures after recovery, but the underlying risk factors are still controversial. Here, we investigated whether (i) the odds of experiencing persistent cognitive failures differ based on the patients' disease course severity and sex at birth; and (ii) the patients' electrolytic profile in the acute stage represents a risk factor for persistent cognitive failures. We analysed data from 204 patients suffering from COVID-19 and hospitalised during the first pandemic wave. According to the 7-point WHO-OS scale, their disease course was classified as severe or mild. We investigated the presence of persistent cognitive failures collected after hospital discharge, while electrolyte profiles were collected during hospitalisation. The results showed that females who suffered from a mild course compared to a severe course of COVID-19 had a higher risk of presenting with persistent mental fatigue after recovery. Furthermore, in females who suffered from a mild course of COVID-19, persistent mental fatigue was related to electrolyte imbalance, in terms of both hypo- and hypernatremia, during hospitalisation in the acute phase. These findings have important implications for the clinical management of hospitalised COVID-19 patients. Attention should be paid to potential electrolyte imbalances, mainly in females suffering from mild COVID-19.
RESUMO
Introduction: The mechanisms subtending the increased stroke risk in migraine with aura (MA) are not fully understood. Our study aims to evaluate if the clinical profile in stroke patients with MA differentiates from those without MA. Methods: We retrieved the prospective registered electronic clinical dossiers of adult patients younger than 60 years with acute ischemic stroke admitted in four hospitals between January 2016 and June 2022. Patients were classified by the history of MA (MA+ and MA-). Results: We identified 851 stroke patients (59 MA+, 6.9%). Compared to MA-, MA+ patients were characterized by younger age (44.0 ± 10.6 vs 50.1 ± 8.2 years), female sex (59.3% vs 29.0%), and affected by cryptogenic (OR 2.594 95% CI 1.483-4.537), and cerebellar stroke (OR 3.218 95% CI 1.657-6.250; p ≤ 0.001 for all comparisons). After adjusting for age and sex, MA+ patients presented less frequently hypertension (OR 0.349 95% CI 0.167-0.470; p=0.005) and dyslipidemia (OR 0.523 95% CI 0.280-0.974; p = 0.041). After adjusting also for risk factors, the MA+ group had less frequently symptomatic large vessel stenosis (OR 0.126 95% CI 0.017-0,924; p = 0.042) and clinical atherosclerosis (OR 0.103 95% CI 0.014-0.761; p = 0.026), while intima-media thickness did not differ (p = 0.395). Discussion: Cryptogenic and cerebellar stroke and fewer vascular risk factors and clinical atherosclerosis seem to characterize stroke patients with MA.
RESUMO
BACKGROUND: The benefit of distinguishing between disabling versus nondisabling deficit in mild acute ischemic stroke due to endovascular thrombectomy-targetable vessel occlusion (EVT-tVO; including anterior circulation large and medium-vessel occlusion) is unknown. We compared safety and efficacy of acute reperfusion treatments in disabling versus nondisabling mild EVT-tVO. METHODS: From the Safe Implementation of Treatments in Stroke-International Stroke Thrombolysis Register, we included consecutive acute ischemic stroke patients (2015-2021) treated within 4.5 hours, with full NIHSS items availability and score ≤5, evidence of intracranial internal carotid artery, M1, A1-2, or M2-3 occlusion. After propensity score matching, we compared efficacy (3-month modified Rankin Scale score of 0-1, modified Rankin Scale score of 0-2, and early neurological improvement) and safety (nonhemorrhagic early neurological deterioration, any intracerebral or subarachnoid hemorrhage, symptomatic intracranial hemorrhage, and death at 3-month) outcomes in disabling versus nondisabling patients-adopting an available definition. RESULTS: We included 1459 patients. Propensity score matched analysis of disabling versus nondisabling EVT-tVO (n=336 per group) found no significant differences in efficacy (modified Rankin Scale score 0-1: 67.4% versus 71.5%, P=0.336; modified Rankin Scale score 0-2: 77.1% versus 77.6%, P=0.895; early neurological improvement: 38.3% versus 44.4%, P=0.132) and safety (nonhemorrhagic early neurological deterioration: 8.5% versus 8.0%, P=0.830; any intracerebral hemorrhage or subarachnoid hemorrhage: 12.5% versus 13.3%, P=0.792; symptomatic intracranial hemorrhage: 2.6% versus 3.4%, P=0.598; and 3-month death: 9.8% versus 9.2%, P=0.844) outcomes. CONCLUSIONS: We found similar safety and efficacy outcomes after acute reperfusion treatment in disabling versus nondisabling mild EVT-tVO; our findings suggest to adopt similar acute treatment approaches in the 2 groups. Randomized data are needed to clarify the best reperfusion treatment in mild EVT-tVO.

In recent years, several disease-modifying therapies have been developed for the treatment of multiple sclerosis (MS). Cladribine transiently depletes B and T lymphocytes, with subsequent gradual cell recovery. No cases are reported in literature describing Cladribine drug-induced liver injury (DILI). We describe the case of a 19-year-old woman who developed acute idiosyncratic liver injury 12 days after treatment with Cladribine. Post-marketing adverse event reporting is of paramount importance to allow an early recognition and treatment. Moreover, evaluation of the physiopathological mechanism underlying drug-induced hepatic toxicity can provide clinicians with valuable instruments for prevention and treatment.

Insomnia affects one-third of the adult population and is associated with multiple medical conditions. We conducted an observational epidemiological survey to assess (1) the prevalence of insomnia in an Italian group of patients aged over 50 years, presenting directly to the general physician (GP); (2) the association of insomnia with sleepiness and comorbidities; and (3) the pharmacological treatment. The study was carried out by GPs. Each GP was asked to enroll the first patient over 50 years old spontaneously presenting for any medical problems for 5 consecutive days. The Italian version of the Sleep Condition Indicator (SCI) was administered; daytime sleepiness was evaluated by a visual analogic scale (VAS). For every patient, GPs collected information regarding comorbidities and pharmacological treatment for insomnia and evaluated the severity of insomnia using the Clinical Global Impression Severity (CGI-S) scale. A total of 748 patients (mean age 65.12 ± 9.45 years) were enrolled by 149 GPs. Prevalence of insomnia was 55.3%. SCI, VAS, and CGI-S scores were highly correlated between each other (p < 0.0001). At general linear model analysis, the comorbidities more associated with the presence of insomnia were anxiety-depressive disorder (p < 0.001), other psychiatric disorders (p = 0.017), cardiovascular disorders (p = 0.006), and dementia (p = 0.027). A statistically significant correlation was found between SCI score and the use of benzodiazepines (p < 0.001), z-drugs (p = 0.012), antidepressants (p < 0.001), and melatonin-prolonged release (p < 0.001). Insomnia affects half of Italian primary care patients over 50 years and is frequently associated with different medical conditions, sleepiness, and use of multiple-often off-label-drugs.

INTRODUCTION: Narcolepsy is a chronic and rare hypersomnia of central origin characterized by excessive daytime sleepiness and a complex array of symptoms as well as by several medical comorbidities. With growing pharmacological options, polytherapy may increase the possibility of a patient-centered management of narcolepsy symptoms. The aims of our study are to describe a large cohort of Italian patients with narcolepsy who were candidates for pitolisant treatment and to compare patients' subgroups based on current drug prescription (drug-naïve patients in whom pitolisant was the first-choice treatment, switching to pitolisant from other monotherapy treatments, and adding on in polytherapy). METHODS: We conducted a cross-sectional survey based on Italian data from the inclusion visits of the Post Authorization Safety Study of pitolisant, a 5-year observational, multicenter, international study. RESULTS: One hundred ninety-one patients were enrolled (76.4% with narcolepsy type 1 and 23.6% with narcolepsy type 2). Most patients (63.4%) presented at least one comorbidity, mainly cardiovascular and psychiatric. Pitolisant was prescribed as an add-on treatment in 120/191 patients (62.8%), as switch from other therapies in 42/191 (22.0%), and as a first-line treatment in 29/191 (15.2%). Drug-naive patients presented more severe sleepiness, lower functional status, and a higher incidence of depressive symptoms. CONCLUSION: Our study presents the picture of a large cohort of Italian patients with narcolepsy who were prescribed with pitolisant, suggesting that polytherapy is highly frequent to tailor a patient-centered approach.

INTRODUCTION: Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a prothrombotic syndrome observed after adenoviral vector-based vaccines for severe acute respiratory syndrome coronavirus 2. It is characterized by thrombocytopenia, systemic activation of coagulation, extensive venous thrombosis, and anti-platelet factor 4 antibodies. Arterial thrombosis is less common and mainly affects the aorta, peripheral arteries, heart, and brain. Several cases of ischemic stroke have been reported in VITT, often associated with large vessel occlusion (LVO). Here, we describe a case of ischemic stroke with LVO after Ad26.COV2.S vaccine, then we systematically reviewed the published cases of ischemic stroke and VITT following COVID-19 vaccination. METHODS: We describe a 58-year-old woman who developed a thrombotic thrombocytopenia syndrome with extensive splanchnic vein thrombosis and ischemic stroke due to right middle cerebral artery (MCA) occlusion, 13 days after receiving Ad26.COV2.S vaccination. Then, we performed a systematic review of the literature until December 3, 2021 using PubMed and EMBASE databases. The following keywords were used: ("COVID-19 vaccine") AND ("stroke"), ("COVID-19 vaccine") AND ("thrombotic thrombocytopenia"). We have selected all cases of ischemic stroke in VITT. RESULTS: Our study included 24 patients. The majority of the patients were females (79.2%) and younger than 60 years of age (median age 45.5 years). Almost all patients (96%) received the first dose of an adenoviral vector-based vaccine. Ischemic stroke was the presenting symptom in 18 patients (75%). Splanchnic venous thrombosis was found in 10 patients, and cerebral venous thrombosis in 5 patients (21%). Most patients (87.5%) had an anterior circulation stroke, mainly involving MCA. Seventeen patients (71%) had an intracranial LVO. We found a high prevalence of large intraluminal thrombi (7 patients) and free-floating thrombus (3 patients) in extracranial vessels, such as the carotid artery, in the absence of underlying atherosclerotic disease. Acute reperfusion therapy was performed in 7 of the 17 patients with LVO (41%). One patient with a normal platelet count underwent intravenous thrombolysis with alteplase, while 6 patients underwent mechanical thrombectomy. A malignant infarct occurred in 9 patients and decompressive hemicraniectomy was performed in 7 patients. Five patients died (21%). CONCLUSION: Our study points out that, in addition to cerebral venous thrombosis, adenoviral vector-based vaccines also appear to have a cerebral arterial thrombotic risk, and clinicians should be aware that ischemic stroke with LVO, although rare, could represent a clinical presentation of VITT.

OBJECTIVES: Ischemic stroke is a leading cause of death and disability worldwide. For patients with large vessel occlusion stroke, endovascular treatment is now the most effective treatment. We aimed to assess the outcome of patients undergoing endovascular treatment for large vessel occlusion stroke in a real-world setting, comparing our results with data from randomized clinical trials, and recognizing the factors associated with prognosis. MATERIALS AND METHODS: We retrospectively collected data on endovascular procedures performed in one comprehensive stroke center in consecutive patients presenting with large vessel occlusion stroke from January 2017 to January 2020. Data on baseline clinical, imaging, and treatment-related characteristics were recorded. Selection of patients and treatment approach was not standardized but followed current guidelines for ischemic stroke. Functional outcome was evaluated 3 months after endovascular treatment. Clinical, imaging and treatment-related variables associated to outcome were evaluated with univariate and multivariable analyses. RESULTS: Four hundred twelve patients were included in our study. Three-month functional independence was achieved in 50.5% of patients (50.3% in the anterior stroke and 52.1% in the posterior stroke subgroup). Successful arterial reperfusion was observed in 84.3% of patients. Age (odds ratio [OR] 0.41, 95% confidence interval [CI] 0.20-0.87, p = 0.020]), severe stroke at onset (OR 0.40, 95%CI 0.19-0.83), procedure related complications (OR 0.45, 95%CI 0.20-0.99), and good collateral circulation (OR 2.69, 95%CI 1.17-6.16) were associated with 3-month functional independence in multivariable model. CONCLUSIONS: Our real-world outcome results are in line with data from large randomized clinical trials on endovascular treatment for large vessel occlusion stroke.

INTRODUCTION: From the beginning of the COVID-19 pandemic, healthcare workers had to face unprecedented emergency needs associated with an extraordinary amount of psychological distress. In this cross-sectional multicenter study, we investigated sleep disturbances, and the level of anxiety and depression among the healthcare and non-healthcare staff of three hospitals in Milan (Italy) during the COVID-19 outbreak. Moreover, we explored potential predisposing factors for affective symptoms and poor sleep. METHODS: Between June and July 2020, we administered an online questionnaire to evaluate the presence of sleep disorders (Pittsburgh Sleep Quality Index), insomnia (Sleep Condition Indicator), anxiety (State Trait Anxiety Inventory), and depression (Beck Depression Inventory-II). We used univariate and multivariate analysis to evaluate the association between the personal conditions and sleep and affective disorders. RESULTS: The 964 participants reported high rates of sleep disorders (80.3%)-mainly insomnia (30.5%)-anxiety (69.7%), and depression (32.8%). The multivariate analysis showed a strong association of sleep disorders, especially insomnia, with female gender (p = 0.004), divorced marital status (p = 0.015), self-isolation (p = 0.037), and chronic diseases (p = 0.003). Anxiety was significantly associated with teleworking (p = 0.001), while depressive symptoms were associated with self-isolation (p = 0.028), modified work schedules (p = 0.03), and chronic diseases (p = 0.027). CONCLUSION: In hospital workers, the high prevalence of sleep and psychiatric symptoms during the COVID-19 outbreak appears to be determined mainly by modifications of personal or work habits. Teleworking was associated with increased anxiety. An accurate planning of hospital activities and a psychological support are needed to prevent and manage sleep and mental disorders.

BACKGROUND: Patients suffering from stroke in the acute/post-acute phases often present with depressive mood - which negatively impacts on patients' prognosis. However, psychometric evaluation of mood in acute stroke patients may be challenging due to cognitive deficits. Tools investigating emotional states via a vertical analogue line may overcome language/visuo-spatial disorders. This study thus aimed at (a) investigating the clinical usability of a Visual Analogue Mood Scale (VAMS) in acute stroke patients and (b) investigating the interplay between mood and cognition in this population. METHODS: Forty-one acute stroke patients were compared to 41 age-, education- and sex-matched healthy participants (HPs) on the VAMS and on cognitive measures (mental performance in acute stroke, MEPS). A control line bisection (LB) task was administered to control for potential visuo-spatial deficits in patients. RESULTS: Patients reported higher depression levels than HPs (lower VAMS scores); this between-group difference stayed significant when covarying for LB scores. MEPS scores discriminated patients from HPs; among cognitive measures, only the Clock drawing test (CDT) was positively associated with VAMS scores. Lesion side did not affect patients' mood state; however, disease duration was inversely related to VAMS scores. DISCUSSION: The VAMS proved to be a suitable tool for assessing mood in acute stroke patients, as being independent from post-stroke cognitive sequelae. The CDT might represent an adequate measure of depression-induced, post-stroke cognitive efficiency decrease. Mood disorders might occur and thus should be adequately addressed also in post-acute phases - likely due to longer hospitalization times and regression of anosognosic features.
