Background: Sleep disorders in multiple sclerosis (MS) patients are common. Dimethylfumarate is an oral disease-modifying drug (DMT), whose impact on sleep is unknown. Objective: The aim of this study was to characterize actigraphic patterns in MS patients treated with dimethylfumarate. Methods: Twenty relapsing-remitting MS patients with low to a mild disability, aged 20-50y, treated with dimethylfumarate for more than 6 months, were enrolled. All subjects had no history of sleep disorders. Actigraphy was used to study sleep patterns during a seven-day period. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Twenty healthy subjects served as controls. Results: Our results showed statistically significant differences between some actigraphic patterns in MS patients treated with dimethylfumarate and healthy subjects, but the values for patients were still within normal limits. PSQI score was higher in MS patients compared to controls. Conclusions: Our findings suggest that dimethylfumarate, an oral DMT with a favourable benefit-risk profile, does not strongly alter sleep patterns in MS patients with low to mild disability and with no history of sleep disorders. Actigraphy is a simple diagnostic tool, able to support an objective measure of sleep parameters. The simplicity of application may allow considering its use for a screening of sleep disorders in MS patients.

Migraine attack is characterized by disabling pain and associated symptoms. Triptans represent the "gold standard" therapy, but cardiac subjects have significant limitations for this approach. New drug families are under consideration to expand therapeutic offerings, especially in the presence of contraindications or for non-responsive patients. This review aimed to analyze studies related to the category of "ditans," with a focus on lasmiditan, which is available for human use.We consulted PubMed/MEDLINE, Web of Science, and www.gov to find both original and review articles on the mechanism of action of 5-HT1F agonists in migraine, and for randomized, double-blind, placebo-controlled trials (RCTs) on the family of drugs called "ditans," with a focus on "lasmiditan," published in the time frame of 01-Jan-2010 to 31-Mar-2022. Only studies conducted in human subjects and published in English were included in this review.We retrieved four RCTs (named SAMURAI, SPARTAN, GLADIATOR, and CENTURION) and several studies that analyzed the efficacy and safety of lasmiditan. Lasmiditan at increasing doses showed significant improvement in pain and most other troublesome symptoms at 2 h. Adverse events were mild and mainly represented by dizziness, vertigo, drowsiness, and fatigue. No vasoconstrictive effects were described, suggesting the use of ditans as a safe option in chronic cardio- and cerebro-vascular disease.Lasmiditan could be a viable alternative to triptans, although further RCT studies and real-world evidence are needed to better understand its potential and possible adverse events in a larger population.

Background: Sex-related differences in the prevalence and clinical presentation of Obstructive Sleep Apnea Syndrome (OSAS) have been widely documented. The aim of this study was to investigate the influence of patients’ sex on polygraphic parameters with particular attention to sleep autonomic changes in a population of OSAS patients. Methods: Sixty OSAS patients aged 55-65 years (30 men, 30 women) were enrolled. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) and daytime sleepiness with the Epworth Sleepiness Scale (ESS). The presence of respiratory events and autonomic changes during the night was investigated by polygraphy. Results : Similar main cardiovascular risk factors prevalence was observed in both men and women. We observed a significant difference in PSQI (higher in women, p=0.0001) and ESS (higher in men, p=0.004) scores. Snoring (p=0.033), supine AHI (p=0.004), T90 (p=0.021), LO2 (p=0.0001), LF/HF ratio and LF (p=0.0001) were significantly higher in men. Sex differences in PSQI mean score and LF/HF ratio variability were preserved in all the subgroups of OSA severity. Conclusion: The influence of sex in modulating cardiovascular risk is a widely discussed topic. In our study, men showed more severe polygraphic parameters and an increase in LF/HF ratio compared to women. The results of our investigation suggest the relevance of delivering information about the different expressions of OSAS in men and women in order to improve diagnostic skills and in-depth prevention approaches.

Introduction Intravenous thrombolysis (IT) and mechanical thrombectomy (MT) have significantly changed the clinical outcome of acute ischaemic stroke (AIS). Concerns about possible complications often reduce the use of these treatment options for older patients, preferentially managed with antiplatelet therapy (AT). Aim of this study was to evaluate, in a population of middle-old (75–84 years) and oldest-old (≥ 85 years) subjects, the efficacy and safety of different treatments for AIS (IT, IT + MT, MT or AT), mortality and incidence of serious complications. Patients and methods All patients aged over 75 years admitted for AIS in two Stroke Units were enrolled. The physician in each case considered all treatment options and chose the best approach. NIHSS and modified Rankin Scale (mRS) were obtained and differences between admission and discharge scores, defined as delta(NIHSS) and delta(mRS), were calculated. The relationship between delta(NIHSS), delta(mRS) and type of procedure was analysed with a GLM/Multivariate model. Differences in mortality and incidence of serious complications were analysed with the chi-square test. Results A total of 273 patients, mean age 84.07 (± 5.47) years, were included. The Delta(NIHSS) was significantly lower in patients treated with AT than in those treated with IT and MT (p p p Conclusions Our results suggest that IT and AT are effective and relatively safe approaches in middle-aged and older patients.

Obstructive sleep apnea (OSA) is the most prevalent sleep-related breathing disorder, with a negative impact on cardiovascular health. Different OSA symptoms and treatment response in males and females have been reported. The aim of this study was to investigate inflammatory markers in patients with OSA and the relationship of those markers to disease severity in male and female subjects.We considered consecutive subjects referred to the outpatient Sleep Disorder Service of the Respiratory Medicine Department, San Marino Hospital. We included patients with a diagnosis of moderate or severe OSAS and an age range of 45-80 years. Concomitant inflammatory conditions were an exclusion criterion. A polygraphic study and a blood draw for inflammatory markers were performed for each subject.Of 110 subjects, 59 were males. Severe OSA affected 72 subjects. We analyzed data through a 4-level categorical variable according to sex and OSA severity (moderate OSA, males; severe OSA, males; moderate OSA, females; severe OSA, females), which showed significant differences for interleukin-6 (IL-6) and C-reactive protein (CRP) levels. A significant difference in IL-6 levels with a significant ascending trend (p = 0.045) from females with moderate OSAS to males with severe OSAS emerged in our pairwise comparison for estimated marginal means. Also, a significant trend (p = 0.0001) for CRP levels from males with moderate OSAS to females with severe OSAS was shown.OSA and inflammation are interconnected, and both are associated with vascular diseases. Sex-related differences in OSA phenotypes may help the clinicians aim for a more personalized approach.

Chronische Atemwegserkrankungen stellen eine weltweite Epidemie dar. Ihre Inzidenz und Prävalenz in der Weltbevölkerung nimmt zu, und insbesondere bei älteren Menschen treten sie häufig in Verbindung mit anderen Krankheiten auf, was häufig zu einen Status hoher klinischer Komplexität. Fachärzte für Neurologie, Innere Medizin und Pneumologen sollten sich des gemeinsamen Hintergrunds dieser Erkrankungen bewusst sein, um den komorbiden Zustand des Patienten richtig zu behandeln und die Therapie unter Berücksichtigung möglicher Überschneidungen zu optimieren. In dieser Übersichtsarbeit konzentrieren wir uns auf die Beziehungen zwischen chronischen Atemwegserkrankungen und chronischen neurodegenerativen Erkrankungen auf verschiedenen Ebenen; wir untersuchen die gemeinsamen Risikofaktoren und die Wechselwirkungen zwischen den Erkrankungen, die Indikationen für die Untersuchung der Atemfunktion bei neurodegenerativen Erkrankungen und die Wechselwirkungen zwischen Pathologie und Pathologie sowie zwischen Medikamenten und Pathologie bei Patienten, die sowohl von chronischen neurologischen als auch von respiratorischen Krankheiten betroffen sind.

Background: Randomized controlled trials (RCTs) proved that short-term (21–90 days) dual antiplatelet therapy (DAPT) reduces the risk of early ischemic recurrences after a noncardioembolic minor stroke or high-risk transient ischemic attack (TIA) without substantially increasing the hemorrhagic risk. We aimed at understanding whether and how real-world use of DAPT differs from RCTs. Methods: READAPT (Real-Life Study on Short-Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or TIA) is a prospective cohort study including >18-year-old patients treated with DAPT after a noncardioembolic minor ischemic stroke or high-risk TIA from 51 Italian centers. The study comprises a 90-day follow-up from symptom onset. In the present work, we reported descriptive statistics of baseline data of patients recruited up to July 31, 2022, and proportions of patients who would have been excluded from RCTs. We compared categorical data through the χ² test. Results: We evaluated 1070 patients, who had 72 (interquartile range, 62–79) years median age, were mostly Caucasian (1045; 97.7%), and were men (711; 66.4%). Among the 726 (67.9%) patients with ischemic stroke, 226 (31.1%) did not meet the RCT inclusion criteria because of National Institutes of Health Stroke Scale score >3 and 50 (6.9%) because of National Institutes of Health Stroke Scale score >5. Among the 344 (32.1%) patients with TIA, 69 (19.7%) did not meet the RCT criteria because of age, blood pressure, clinical features, duration of TIA, presence of diabetes score 24 hours) DAPT initiation; 776 (72.5%) and 676 (63.2%) patients did not take loading doses of aspirin and clopidogrel, respectively. Overall, 84 (7.8%) patients met the RCT inclusion/exclusion criteria. Conclusions: The real-world use of DAPT is broader than RCTs. Most patients did not meet the RCT criteria because of the severity of ischemic stroke, lower risk of TIA, late DAPT start, or lack of antiplatelet loading dose.

We performed an actigraphic assessment of sleep characteristics in healthy subjects and patients with cognitive impairment. Thirty subjects were included and classified into controls (10 subjects), mild cognitive impairment (10 patients) and mild-to-moderate Alzheimer’s disease (10 patients). Sleep quality was assessed using the Pittsburgh Sleep Quality Index. Participants had a 7-day actigraphic record. Sleep parameters collected were time in bed, total sleep time, sleep efficiency, sleep latency, wakefulness after sleep onset, number of awakenings, and mean motor activity. Significant differences between mild cognitive impairment and controls patients were found for sleep latency (p = 0.05); Alzheimer’s disease patients had significantly worse scores for Pittsburgh Sleep Quality Index (p = 0.01), time in bed (p = 0.001), total sleep time (p = 0.04), sleep latency, sleep efficiency, motor activity (p = 0.0001) and wakefulness after sleep onset (p = 0.001) compared to controls. When comparing Alzheimer’s disease and mild cognitive impairment, differences were significant for sleep latency (p = 0.01), wakefulness after sleep onset (p = 0.004), sleep efficiency, number of awakenings and motor activity (p = 0.0001). In addition to showing a high prevalence of sleep alterations in subjects with cognitive impairment, our data suggest that they are evident from the earliest stages of cognitive decline. Further studies are needed to assess whether early correction of sleep alterations can positively influence the evolution of cognitive impairment. The opportunity to provide clinically meaningful information with a simple assessment of sleep characteristics based on actigraphy suggests that wider use of the approach in patients with cognitive decline should be considered.

Chronic respiratory disorders represent a world epidemic. Their incidence and prevalence in the world population is increasing, and especially among elderly subjects, they are commonly associated with other pathologies, often generating a status of high clinical complexity. Neurology, internal medicine, and pneumology specialists should be aware of the common background of these disorders in order to treat correctly the patient’s comorbid state and optimize the treatment considering potential overlaps. In this review, we aimed to focus on the relationships between chronic respiratory disorders and chronic neurodegenerative diseases at different levels; we review the shared risk factors and the interactions between disorders, the indications to explore respiratory function in neurodegenerative diseases, pathology-pathology and drug-pathology interactions in patients affected by both chronic neurologic and respiratory diseases.

To reduce intensive care unit overcrowding and optimize resources, elderly patients affected by suspected infection with declining clinical conditions could be managed in internal medicine departments with stepdown beds. However, commonly used prognostic scores, as Sequential Organ Failure Assessment (SOFA) or quick SOFA (qSOFA) have never been studied in this specific setting. The aim of this study was to evaluate the role and the accuracy of SOFA and qSOFA as prognostic scores in a population of elderly patients with suspected infection admitted to stepdown beds of two internal medicine departments. Elderly patients admitted from the emergency department in the stepdown beds of two different internal medicine departments for suspected infection were assessed with SOFA and qSOFA scores at the admission. All patients were treated according to current guidelines. Age, sex, comorbidities, Charlson comorbidity index, SOFA and qSOFA were assessed. In-hospital death and length of hospital admission were also recorded. 390 subjects were enrolled. In-hospital death occurred in 144 (36.9%) patients; we observed that both SOFA (HR 1.189; 95% CI 1.128–1.253; p

Data regarding further risk stratification of intermediate-risk pulmonary embolism (IR-PE) are scanty. Whether transthoracic echocardiography may be helpful in further risk assessment of death in such population has still to be proven. Two-hundred fifty-four consecutive patients (51.6% females, age 63.7 ± 17.3 years) with IR-PE admitted to a tertiary regional referral center were enrolled. Patients underwent a complete transthoracic echocardiography within 36 h from hospital admission, on top of clinical assessment, physical examination, computer tomography pulmonary angiography (CTPA), and serum measurement of Troponin I (TnI) levels. The occurrence of 90 day mortality was chosen as primary outcome measure. When compared to survivors, non-surviving IR-PE patients had smaller left-ventricular end-diastolic volumes (39.8 ± 20.9 vs 49.4 ± 19.9 ml/m2, p = 0.006) with reduced stroke volume index (SVi) (24.7 ± 10.9 vs 30.9 ± 12.6 ml/m2, p: 0.004) and time–velocity integral at left-ventricular outflow tract (VTILVOT) (0.17 ± 0.03 vs 0.20 ± 0.04 m, p = 0.0001), whereas no differences were recorded regarding right heart parameters. Cox regression analysis revealed that right atrial enlargement (RAE) (HR 3.432, 5–95% CI 1.193–9.876, p: 0.022), the ratio between tricuspid annulus plane excursion and pulmonary arterial systolic pressure (TAPSE/PASp) (HR 4.833, 5–95% 1.230–18.986, p = 0.024), as well as SVi (HR 11.199, 5–95% CI 2.697–48.096, p = 0.001) and VTILVOT (HR 4.212, 5–95% CI 1.384–12.820, p = 0.011) were powerful independent predictors of mortality. Neither CTPA RV/LV nor TnI resulted associated with impaired survival. In intermediate-risk pulmonary embolism, RAE, TAPSE/PASp ratio, SVi, and VTILVOT predict independently prognosis to a greater extent than CTPA and TnI.

Critically ill patients affected by atrial fibrillation are at high risk of adverse events: however, the actual risk stratification models for haemorrhagic and thrombotic events are not validated in a critical care setting. With this paper we aimed to identify, adopting topological data analysis, the risk factors for therapeutic failure (in-hospital death or intensive care unit transfer), the in-hospital occurrence of stroke/TIA and major bleeding in a cohort of critically ill patients with pre-existing atrial fibrillation admitted to a stepdown unit; to engineer newer prediction models based on machine learning in the same cohort. We selected all medical patients admitted for critical illness and a history of pre-existing atrial fibrillation in the timeframe 01/01/2002–03/08/2007. All data regarding patients’ medical history, comorbidities, drugs adopted, vital parameters and outcomes (therapeutic failure, stroke/TIA and major bleeding) were acquired from electronic medical records. Risk factors for each outcome were analyzed adopting topological data analysis. Machine learning was used to generate three different predictive models. We were able to identify specific risk factors and to engineer dedicated clinical prediction models for therapeutic failure (AUC: 0.974, 95%CI: 0.934–0.975), stroke/TIA (AUC: 0.931, 95%CI: 0.896–0.940; Brier score: 0.13) and major bleeding (AUC: 0.930:0.911–0.939; Brier score: 0.09) in critically-ill patients, which were able to predict accurately their respective clinical outcomes. Topological data analysis and machine learning techniques represent a concrete viewpoint for the physician to predict the risk at the patients’ level, aiding the selection of the best therapeutic strategy in critically ill patients affected by pre-existing atrial fibrillation.

Background Growing evidence suggests that hyperhomocysteinemia (HHcy) constitutes a risk factor for Alzheimer’s Disease (AD). The impact of HHcy on cognitive functions has mainly been investigated using screening neuropsychological tests that provide general, unspecific measures of cognitive level. Since an association between HHcy and temporo-mesial atrophy has been documented, we predicted that a fine-grained analysis of neuropsychological performance should show stronger Hcy effects on memory scores than on other cognitive scores. Objective To determine the influence of Hcy level on cognitive profile evaluated with specific, sensitive neuropsychological tests in a wide AD cohort. Methods 323 patients with AD were enrolled in a cross-sectional study and underwent a neuropsychological examination exploring several cognitive domains (memory, language, visuoperception, visuospatial abilities, executive function, constructional praxis, ideomotor praxis). The effects of Hcy levels and other risk factors (including cholesterol, smoking habits, triglycerides, apoEe4 allele) were analysed. Results Generalized Linear Model detected a significant drop in performance with increasing Hcy in 6/19 measures of cognitive functions, namely, in memory performance tasks as well as in Luria’s motor planning test, with effect sizes ranging 1.4%–2.8% (Eta-squared), partialling out effects of other predictors. Conclusions HHcy was associated with poor performance in short and long-term spatial and verbal memory more than with other cognitive dysfunctions. These results support the hypothesis that medial temporal networks might be vulnerable to HHcy, consistently with data from neuroimaging studies suggesting a link in AD between temporal atrophy and HHcy; the effect on Luria’s motor planning task suggests further involvement of frontal structures.

Polycythemia vera (PV) is a myeloproliferative disorder associated with an increased risk of cerebrovascular diseases. In this narrative review, we aimed to analyze the relationships between acute ischemic stroke and PV. We conducted a PubMed/Medline and Web of Sciences Database search using MeSH major terms. We found 75 articles and finally considered 12 case reports and 11 cohort studies. The ischemic stroke resulted as the first manifestation of PV in up to 16.2% of cases; the cumulative rate of cerebrovascular events was up to 5.5 per 100 persons per year and stroke accounted for 8.8% of all PV-related deaths; age, mutations, and a previous history of thrombosis were the main risk factors. The best approach to reduce stroke recurrence risk is unclear, even if some evidence suggests a potential role of lowering hematocrit below 45%. Ischemic stroke represents one of the most common PV manifestations but, despite their relationship, patients with both diseases have a very heterogeneous clinical course and management. PV-related strokes often remain underdiagnosed, especially for the low prevalence of PV. An early diagnosis could lead to prompt treatment with phlebotomy, cytoreduction, and low-dose aspirin to decrease the risk of recurrences. Clinicians should be aware of PV as a risk factor for stroke when approaching the differential diagnosis of cryptogenic strokes. An early diagnosis could positively influence patients’ management and clinical outcomes. Further studies are required to evaluate the role of PV treatments in the prevention of cerebrovascular disease.

Objective Sleep plays a role in some oligodendrocyte processes, including myelination. This study aimed to analyze the possible correlations between sleep quality and Multiple Sclerosis (MS) course. Methods Forty patients with Relapsing-Remitting MS were admitted. Based on the score obtained at the Pittsburgh Sleep Quality Index (PSQI), they were divided into good sleepers (

To identify the clinical profile and aura characteristics of patients with Migraine with Aura (MwA) having acute cerebral ischemia, we compared stroke phenotype and risk factors in stroke patients with (S+MwA+) or without (S+MwA−) MwA and aura features in MwA patients with (S+MwA+) or without (S−MwA+) stroke. In this retrospective multicenter case–control study, we reviewed stroke phenotypes and vascular risk factors in S+MwA+ and S+MwA− patients younger than 60 years and risk factors and aura type, duration, onset age, and the frequency in the previous year in S+MwA+ patients and S−MwA+ subjects matched for age and disease history, investigated for patent foramen ovale (PFO). 539 stroke (7.7% S+MwA+) and 94 S−MwA + patients were enrolled. S+MwA+ patients were younger (p =.0.004) and more frequently presented PFO [OR 4.89 (95% CI 2.12–11.27)], septal interatrial aneurism [OR 2.69 (95% CI 1.15–6.27)] and cryptogenic ischemic stroke (CIS) [OR 6.80 (95% CI 3.26–14.18)] than S+MwA− subjects. Significant atherosclerosis was not detected in S+MwA+ patients. Compared to S−MwA+, S+MwA+ patients were characterized by visual [OR 3.82 (95% CI 1.36–10.66)] and shorter-lasting (20.0 min IQr 13.1 vs 30.0 min IQr 25.0; p

Headache is considered as a possible complication of dialytic treatment in chronic kidney disease (CKD). The aim of this study was to evaluate possible change in headache characteristics after kidney transplantation in patients with CKD. During a 1-year period, we enrolled 110 subjects submitted to a kidney transplant in the previous 5 years. Headache characteristics before and after the transplant were investigated by a specific questionnaire. Possible effects of pharmacological therapies were also evaluated. 65.5% of patients complained of headache before the transplant (38.2% migraine and 14.5% dialysis headache). After transplant, 53.6% of patients reported changes in headache characteristics. In particular, 27.3% of the patients had a complete resolution, 19.1% presented a headache improvement and 7.2% showed a worsening. In both migraine and dialysis headache subgroups, steroids, beta-blockers and calcium channel blockers were associated with a significant improvement of headache. Kidney transplantation seems to impact significantly headache frequency and severity in patients with CKD. A careful evaluation and use of targeted treatments could improve both patients’ compliance to therapies and quality of life.

Background QT dispersion, maximal interlead difference in QT interval on 12-lead electrocardiogram (ECG), measures cardiac repolarization abnormalities. Data are conflicting whether QT dispersion predicts adverse outcome in acute ischemic stroke (AIS) patients. Our objective is to determine if QT dispersion predicts: (1) short-term clinical outcome in AIS, and (2) stroke location (insular versus noninsular cortex). Methods Admission ECGs from 412 consecutive patients with acute stroke symptoms from 2 university-based stroke centers were reviewed. QT dispersion was measured. A neuroradiologist reviewed brain imaging for insular cortex involvement. Favorable clinical outcomes at discharge were modified Rankin Scale (mRS) score of 0-1, discharge National Institutes of Health Stroke Scale (NIHSS) score less than 2, and discharge to home. Multiple logistic regressions were performed for each outcome measure and to determine the association between insular infarct and QT dispersion. Results Of 145 subjects in the final analysis, median age was 65 years (interquartile range [IQR] 56-75), male patients were 38%, black patients were 68%, median QT dispersion was 78 milliseconds (IQR 59-98), and median admission NIHSS score was 4 (IQR 2-6). QT dispersion did not predict short-term clinical outcome for mRS score (odds ratio [OR] = 1.001, 95% confidence interval [CI] .99-1.01, P = .85), NIHSS at discharge (OR = .994, 95% CI .98-1.01, P = .30), or discharge disposition (OR = 1.001, 95% CI .99-1.01, P = .81). Insular cortex involvement did not correlate with QT dispersion magnitude (OR = 1.009, 95% CI .99-1.02, P = .45). Conclusions We could not demonstrate that QT dispersion is useful in predicting short-term clinical outcome at discharge in AIS. Further, the magnitude of QT dispersion did not predict insular cortical stroke location.

Carotid atherosclerosis has a relevant impact on cerebral blood flow regulation. There is accruing evidence that hemodynamic impairment related to the presence of a significant carotid lumen narrowing may predispose to the development of cerebral dysfunctions, including a reduction in cognitive abilities. In the last years an increasing number of findings showed that carotid stenosis did contribute to cognitive impairment not only in relation to the occurrence of cerebral ischemic lesions, but also as an independent risk factor. The principal mechanisms involved are chronic hypoperfusion, microembolization and cerebrovascular reactivity impairment. Moreover, more recent studies showed alterations of regional functional connectivity. In this narrative review, we analyzed the relationships between carotid stenosis, cerebral hemodynamic derangement and cognitive impairment onset and progression, and underlined that cognitive impairment is the final result of the complex interaction between different elements, including also collateral circulation, cerebral hemodynamic status, brain connectivity and pro-inflammatory state. Further, therapeutic approaches, with a specific focus on vascular risk factors correction and on the effectiveness of surgical or endovascular interventions were discussed. We particularly focused our attention on the concept of "asymptomatic carotid stenosis", and how could a cognitive impairment improve after an intervention, and how this could change the indications to surgical approach. Larger studies and randomized controlled trials are urgently required to better define time, characteristics and effectiveness of both medical and surgical/endovascular approaches.

Elderly patients affected by suspected infection and declining clinical conditions can be admitted to stepdown units (SDU), but a risk stratification is necessary to optimize their management. Admission troponin I (aTnI) has a prognostic role, however, one of the most commonly used stratification tools, the Sequential Organ Failure Assessment score (SOFA), does not consider myocardial injury. With this paper, we aimed to evaluate the prognostic accuracy of a new score, named SOFA-T, considering both SOFA score and aTnI in a cohort of elderly patients admitted to the stepdown beds of two Internal Medicine departments. Patients aged > 65 years admitted in SDU of two different hospitals of the same region in a 12-months timeframe were retrospectively assessed obtaining age, sex, days of admission, in-hospital death, SOFA, aTnI and comorbidities. The best aTnI cutoff for in-hospital death was calculated with ROC curve analysis; dichotomous variables were compared with chi-squared test; continuous variables were compared with t test or Mann–Whitney test. We obtained a cohort of 390 patients. The best aTnI cutoff was 0.31 ng/ml: patients with increased aTnI had higher risk of in-hospital death (OR: 1.834; 95% CI 1.160–2.900; p = 0.009), and higher SOFA (6.81 ± 2.71 versus 5.97 ± 3.10; p = 0.010). Adding aTnI to SOFA increased significantly the area under the curve (AUCSOFA = 0.68; 95% CI 0.64–0.73; AUCSOFA-T = 0.71; 95% CI 0.65–0.76; p = 0.0001), with a slight improvement of the prognostic performance. In elderly patients admitted to SDU for suspected infection, sepsis or septic shock, aTnI slightly improves the accuracy of SOFA score of the in-hospital death prediction.

Objective To assess whether erenumab influences cerebral vasomotor reactivity and flow-mediated dilation in migraine patients. Methods Consecutive migraineurs prescribed erenumab at our Headache Centre and age and sex-matching controls were invited to participate in this observational longitudinal study. Patients were evaluated for cerebral vasomotor reactivity to hypercapnia (breath-holding index) in middle and posterior cerebral arteries and for brachial corrected flow mediated dilation at baseline (T0), after 2 weeks from the first erenumab injection (T2) and after 2 weeks from the fourth Erenumab injection (T18). Patients displaying a reduction of at least 50% in monthly migraine days after completing the fourth month of therapy were classified as responders. Results Sixty patients and 25 controls agreed to participate. Middle and posterior cerebral artery mean flow velocities, breath-holding index and flow-mediated dilation did not differ at T0 and from T0 to T2 in patients and controls. In patients, we neither observed a variation of the explored variables from T0 to T18 nor an interaction between evaluation times (T0–T2 or T0–T18) and chronic condition at T0, responder state or erenumab fourth dose. Conclusions Our findings demonstrate that erenumab preserves cerebral vasomotor reactivity and flow-mediated dilation in migraineurs without aura.

Sleep disorders in multiple sclerosis (MS) patients are common and complex. Some evidences suggest that interferon beta (IFN-β), a first line disease modifying therapy can be involved in the induction of sleep architecture changes. The aim of this study was to evaluate and characterize actigraphic patterns in MS patients treated with IFN-β.Ten relapsing remitting MS patients with low to mild disability (Expanded Disability Status Scale2.5), aged 20-50y treated with IFN-β for more than 6 months were enrolled. Actigraphy was used to study sleep pattern. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Ten sex-and age-matched healthy subjects served as controls. In patients, a comparison between drug free nights and nights following drug administration was made.Patients had significantly higher PSQI (p = 0.006), sleep onset latency (p = 0.029), sleep efficiency percentage (p = 0.001) and number of wake episodes (p = 0,0001) values, when compared with controls. When comparing the actigraphic results acquired in the nights after treatment with those acquired in the free-drug nights, the only significant difference (p = 0.038) was detected for time in bed that was higher after IFN-β administration.Our results, besides confirming the presence of alterations in sleep patterns in MS patients, suggest that IFN-β may contribute to promote alteration in sleep architecture. Actigraphy is a simple diagnostic tool, able to support an objective measure of sleep parameters. The relative simplicity of application and low costs may allow considering its use for an adequate screening of sleep disorders in MS patients.

Background: Atrial fibrillation (AF) is a risk factor for cerebrovascular diseases and vascular dementia (VAD). The aim of this study was to evaluate the effect of the adherence to anticoagulant therapy guidelines in patients with dementia and AF on the risk of stroke/TIA or major bleeding (MB). Methods: In a cohort of 1705 hospitalized patients with pre-existent AF, we observed 193 patients with vascular dementia (VAD). Non-demented AF patients were included as controls. For each subject, we calculated CHA2DS2-VASc, CHADS2, and HAS-BLED scores, and collected information regarding anticoagulant therapy, in-hospital therapeutic failure (TF) occurrence, stroke/TIA, and MB. Results: According to CHA2DS2-VASc and CHADS2 scores, 99.5% of VAD patients had the indication to anticoagulant treatment, but only 69.9% were correctly treated. During hospitalization, MB occurred in 4.66% of VAD and 8.9% of non-demented patients (p = 0.048). In-hospital stroke/TIA were observed in 24.3% of VAD and 0.8% of non-demented patients (p = 0.0001). A similar proportion of TF among patients with VAD and with normal cognition (12.9% vs. 11.2%) was observed. Conclusion: In our cohort, we observed that VAD patients with pre-existent AF were undertreated despite a higher risk of stroke/TIA with respect to non-demented patients.

BACKGROUND Limited data are available on the clinical course of patients with history of atrial fibrillation (AF) when admitted in an intensive care environment. We aimed to describe the occurrence of major adverse events in AF patients admitted to a stepdown care unit (SDU) and to analyse clinical factors associated with outcomes, impact of dicumarolic oral anticoagulant (OAC) therapy impact and performance of clinical risk scores in this setting. MATERIALS AND METHODS Single-centre, observational retrospective analysis on a population of subjects with AF history admitted to a SDU. Therapeutic failure (composite of transfer to ICU or death) was considered the main study outcome. Occurrence of stroke and major bleeding (MH) was considered as secondary outcomes. The performance of clinical risk scores was evaluated. RESULTS A total of 1430 consecutive patients were enrolled. 194 (13.6%) reported the main outcome. Using multivariate logistic regression, age (odds ratio [OR]: 1.03, 95% confidence interval [CI]: 1.01-1.05), acute coronary syndrome (OR:3.10, 95% CI: 1.88-5.12), cardiogenic shock (OR:10.06, 95% CI: 5.37-18.84), septic shock (OR:5.19,95%CI:3.29-18.84), acute respiratory failure (OR:2.49, 95% CI: 1.67-3.64) and OAC use (OR: 1.61, 95% CI: 1.02-2.55) were independently associated with main outcome. OAC prescription was associated with stroke risk reduction and to both MH and main outcome risk increase. CHA2 DS2 -VASc (c-index: 0.545, P = .117 for stroke) and HAS-BLED (c-index:0.503, P = .900 for MH) did not significantly predict events occurrence. CONCLUSIONS In critically ill AF patients admitted to a SDU, adverse outcomes are highly prevalent. OAC use is associated to an increased risk of therapeutic failure, clinical scores seem unhelpful in predicting stroke and MH, suggesting a highly individualized approach in AF management in this setting.

OBJECTIVES: The aim of this study was to investigate whether the presence of carotid artery occlusion (CO) may be associated with different cognitive performances in relation to the side of the occlusion and its hemodynamic consequences. METHODS: During a 12-month-period, 61 asymptomatic patients, 32 with right and 29 with left CO were enrolled. Each patient underwent an assessment of cerebrovascular reactivity (CVR) to hypercapnia with transcranial Doppler (TCD) ultrasonography using the breath-holding index (BHI). Neuropsychological assessment evaluating performances of the hemisphere ipsilateral to CO were administered at entry (T0 ) and then repeated after two years (T1 ). RESULTS: Scores obtained at Coloured Progressive Matrices (CPM) and Rey Complex Figure Copy Test were significantly lower at T0 in patients with reduced BHI values ipsilateral to CO. Multivariate models showed that reduced BHI values were also associated to a significant decrease from T0 to T1 in scores obtained for CPM and Categorical Verbal Fluency tests respectively in patients with right (P = 0.002) or left CO (P = 0.004). CONCLUSIONS: These findings suggest that hemodynamic alterations could be involved in the reduction in cognitive function regulated by the hemisphere ipsilateral to CO. The assessment of cerebrovascular reactivity with TCD ultrasonography may be a reliable approach for the individuation of asymptomatic patients with CO at increased risk of cognitive deterioration.
