Introduction: Immunosuppressive treatment is effective in most Myasthenia gravis patients, but 10-15% of patients areconsidered refractory due to inadequate response or intolerance to therapy. Eculizumab, a humanized monoclonalantibody directed against C5 complement protein, was approved in Italy to treat Ab-AchR generalized refractoryMG (rMG) in October 2022., Aim: We aim to describe a real-world Italian experience in a population of refractory myasthenia gravis patients with oneyear follow up., Methods: A retrospective data analysis was conducted on patients with refractory generalized MG treated with eculizumabbetween November 2022 and May 2024. Clinical assessment through specific scales (MG ADL - QMG - MGFA -PIS), rescue, and background therapy was recorded after one, three, six, and twelve months., Results: 21 rMG patients were treated with eculizumab with a medium follow up of 10.4 months and 14 patients had at leastone year follow up. A clinically meaningful reduction in total MG-ADL and QMG scores was achieved in the firstmonth. It was maintained throughout the first, third, sixth, and twelfth month along with concomitant reduction ofimmunosuppressive treatments. A drastic reduction of myasthenic exacerbations and crisis was observed duringfollow up and intravenous immunoglobulin treatment was discontinued in all patients except one. The total dailydose of prednisone was significantly reduced., Discussion: This single-center real-world study confirmes safety and effectiveness of eculizumab. Eculizumab improved rapidlyall clinical outcome measures, leading to discontinuation of intravenous immunoglobulin treatment and remarkable immunosuppressant-sparing benefits., Competing Interests: Declarations.

We describe the case of a 45-year-old female affected by asthma and nasal polyposis who presented to the emergency department because of worsening dyspnea and paresthesia of the left lower limb. Comprehensive instrumental examinations revealed the presence of severe left ventricle dysfunction, intra-cardiac thrombus, deep vein thrombosis, pulmonary embolism, lung infiltrates, polyserositis, and neurological involvements. Finally, the patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA), formerly Churg-Strauss syndrome, a rare vasculitis of small-medium blood vessels with several organ involvements. Treatment with anticoagulants, corticosteroids, and cyclophosphamide led to a significant clinical improvement. However, a subcutaneous cardiac defibrillator was implanted because of the persistence of severe left ventricular dysfunction and the high cardiovascular risk phenotype. Indeed, several cardiac manifestations may occur in EGPA, particularly in patients with anti-neutrophil cytoplasmic antibody-negative disease. Therefore, clinicians should have high clinical suspicion because cardiac involvement in EGPA results in a poor prognosis if not diagnosed and adequately treated.

Background and Purpose: There are different criteria for the diagnosis of different variants of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The 2021 European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) guidelines provide specific clinical criteria for each CIDP variant even if their therapeutical impact has not been investigated., Methods: We applied the clinical criteria for CIDP variants of the 2021 EAN/PNS guidelines to 369 patients included in the Italian CIDP database who fulfilled the 2021 EAN/PNS electrodiagnostic criteria for CIDP., Results: According to the 2021 EAN/PNS clinical criteria, 245 patients achieved a clinical diagnosis of typical CIDP or CIDP variant (66%). We identified 106 patients with typical CIDP (29%), 62 distal CIDP (17%), 28 multifocal or focal CIDP (7%), four sensory CIDP (1%), 27 sensory-predominant CIDP (7%), 10 motor CIDP (3%), and eight motor-predominant CIDP (2%). Patients with multifocal, distal, and sensory CIDP had milder impairment and symptoms. Patients with multifocal CIDP had less frequently reduced conduction velocity and prolonged F-wave latency and had lower levels of cerebrospinal fluid protein. Patients with distal CIDP more frequently had reduced distal compound muscle action potentials. Patients with motor CIDP did not improve after steroid therapy, whereas those with motor-predominant CIDP did. None of the patients with sensory CIDP responded to steroids, whereas most of those with sensory-predominant CIDP did., Conclusions: The 2021 EAN/PNS criteria for CIDP allow a better characterization of CIDP variants, permitting their distinction from typical CIDP and more appropriate treatment for patients., (© 2023 The Authors.

Background: Pulmonary vein isolation by cryoablation (PVI-C) is a standard therapy for the treatment of patients with symptomatic atrial fibrillation (AF). AF symptoms are highly subjective; however, they are important outcomes for the patient. The aim is to describe the use and impact of a web-based App to collect AF-related symptoms in a population of patients who underwent PVI-C in seven Italian centers., Methods: A patient App to collect AF-related symptoms and general health status was proposed to all patients who underwent an index PVI-C. Patients were divided into two groups according to the utilization of the App or the non-usage., Results: Out of 865 patients, 353 (41%) subjects composed the App group, and 512 (59%) composed the No-App group. Baseline characteristics were comparable between the two cohorts except for age, sex, type of AF, and body mass index. During a mean follow-up of 7.9±13.8 months, AF recurrence was found in 57/865 (7%) subjects with an annual rate of 7.36% (95% CI:5.67-9.55%) in the No-App versus 10.99% (95% CI:9.67-12.48%) in the App group, p=0.007. In total, 14,458 diaries were sent by the 353 subjects in the App group and 77.1% reported a good health status and no symptoms. In only 518 diaries (3.6%), the patients reported a bad health status, and bad health status was an independent parameter of AF recurrence during follow-up., Conclusions: The use of a web App to record AF-related symptoms was feasible and effective. Additionally, a bad health status reporting in the App was associated with AF recurrence during follow-up., (© 2023. The Author(s).)

Background: There is a paucity of data comparing vitamin K antagonists (VKAs) to direct oral anticoagulants (DOACs) at the time of cardiac implantable electronic device (CIED) surgery. Furthermore, the best management of DOACs (interruption vs continuation) is yet to be determined., Objectives: This study aimed to compare the incidence of device-related bleeds and thrombotic events based on anticoagulant type (DOAC vs VKA) and regimen (interrupted vs uninterrupted)., Methods: This was an observational multicenter study. We included patients on chronic oral anticoagulation undergoing CIED surgery. Patients were matched using propensity scoring., Results: We included 1,975 patients (age 73.8 ± 12.4 years). Among 1,326 patients on DOAC, this was interrupted presurgery in 78.2% (n = 1,039) and continued in 21.8% (n = 287). There were 649 patients on continued VKA. The matched population included 861 patients. The rate of any major bleeding was higher with continued DOAC (5.2%) compared to interrupted DOAC (1.7%) and continued VKA (2.1%) (P = 0.03). The rate of perioperative thromboembolism was 1.4% with interrupted DOAC, whereas no thromboembolic events occurred with DOAC or VKA continuation (P = 0.04). The use of dual antiplatelet therapy, DOAC continuation, and male sex were independent predictors of major bleeding on a multivariable analysis., Conclusions: In this large real-world cohort, a continued DOAC strategy was associated with a higher bleeding risk compared to DOAC interruption or VKA continuation in patients undergoing CIED surgery. However, DOAC interruption was associated with increased thromboembolic risk. Concomitant dual antiplatelet therapy should be avoided whenever clinically possible. A bespoke approach is necessary, with a strategy of minimal DOAC interruption likely to represent the best compromise., Competing Interests: Funding Support and Author Disclosures Dr Creta has received speaker fees from Boston Scientific.

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive neuromodulation technique that is used against cognitive impairment in mild cognitive impairment (MCI) and Alzheimer's disease (AD). However, the neurobiological mechanisms underlying the rTMS therapeutic effects are still only partially investigated. Maladaptive plasticity, glial activation, and neuroinflammation, including metalloproteases (MMPs) activation, might represent new potential targets of the neurodegenerative process and progression from MCI to AD. In this study, we aimed to evaluate the effects of bilateral rTMS over the dorsolateral prefrontal cortex (DLPFC) on plasmatic levels of MMP1, -2, -9, and -10; MMPs-related tissue inhibitors TIMP1 and TIMP2; and cognitive performances in MCI patients. Patients received high-frequency (10 Hz) rTMS (MCI-TMS, n = 9) or sham stimulation (MCI-C, n = 9) daily for four weeks, and they were monitored for six months after TMS. The plasmatic levels of MMPs and TIMPs and the cognitive and behavioral scores, based on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Beck Depression Inventory II, Beck Anxiety Inventory, and Apathy Evaluation Scale, were assessed at baseline (T0) and after 1 month (T1) and 6 months (T2) since rTMS. In the MCI-TMS group, at T2, plasmatic levels of MMP1, -9, and -10 were reduced and paralleled by increased plasmatic levels of TIMP1 and TIMP2 and improvement of visuospatial performances. In conclusion, our findings suggest that targeting DLPFC by rTMS might result in the long-term modulation of the MMPs/TIMPs system in MCI patients and the neurobiological mechanisms associated with MCI progression to dementia.

Background and Purpose: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited treatment options. RNS60 is an immunomodulatory and neuroprotective investigational product that has shown efficacy in animal models of ALS and other neurodegenerative diseases. Its administration has been safe and well tolerated in ALS subjects in previous early phase trials., Methods: This was a phase II, multicentre, randomized, double-blind, placebo-controlled, parallel-group trial. Participants diagnosed with definite, probable or probable laboratory-supported ALS were assigned to receive RNS60 or placebo administered for 24 weeks intravenously (375 ml) once a week and via nebulization (4 ml/day) on non-infusion days, followed by an additional 24 weeks off-treatment. The primary objective was to measure the effects of RNS60 treatment on selected biomarkers of inflammation and neurodegeneration in peripheral blood. Secondary objectives were to measure the effect of RNS60 on functional impairment (ALS Functional Rating Scale-Revised), a measure of self-sufficiency, respiratory function (forced vital capacity, FVC), quality of life (ALS Assessment Questionnaire-40, ALSAQ-40) and survival. Tolerability and safety were assessed., Results: Seventy-four participants were assigned to RNS60 and 73 to placebo. Assessed biomarkers did not differ between arms. The mean rate of decline in FVC and the eating and drinking domain of ALSAQ-40 was slower in the RNS60 arm (FVC, difference 0.41 per week, standard error 0.16, p = 0.0101; ALSAQ-40, difference -0.19 per week, standard error 0.10, p = 0.0319). Adverse events were similar in the two arms. In a post hoc analysis, neurofilament light chain increased over time in bulbar onset placebo participants whilst remaining stable in those treated with RNS60., Conclusions: The positive effects of RNS60 on selected measures of respiratory and bulbar function warrant further investigation., (© 2022 The Authors.

Background: The absence of pacing capabilities may reduce the appeal of subcutaneous implantable cardioverter-defibrillator (S-ICD) devices for patients at risk for conduction disorders or with antitachycardia pacing (ATP)/cardiac resynchronization (CRT) requirements. Reports of rates of S-ICD to transvenous implantable cardioverter-defibrillator (TV-ICD) system switch in real-world scenarios are limited., Objective: The purpose of this study was to investigate the need for a subsequent transvenous (TV) device in patients implanted with an S-ICD and its predictors., Methods: All patients implanted with an S-ICD were enrolled from the multicenter, real-world iSUSI (International SUbcutaneouS Implantable cardioverter defibrillator) Registry. The need for a TV device and its clinical reason, and appropriate and inappropriate device therapies were assessed. Logistic regression with Firth penalization was used to assess the association between baseline and procedural characteristics and the overall need for a subsequent TV device., Results: A total of 1509 patients were enrolled (age 50.8 ± 15.8 years; 76.9% male; 32.0% ischemic; left ventricular ejection fraction 38% [30%-60%]). Over 26.5 [13.4-42.9] months, 155 (10.3%) and 144 (9.3%) patients experienced appropriate and inappropriate device therapies, respectively. Forty-one patients (2.7%) required a TV device (13 bradycardia; 10 need for CRT; 10 inappropriate shocks). Body mass index (BMI) >30 kg/m 2 and chronic kidney disease (CKD) were associated with need for a TV device (odds ratio [OR] 2.57 [1.37-4.81], P = .003; and OR 2.67 [1.29-5.54], P = .008, respectively)., Conclusion: A low rate (2.7%) of conversion from S-ICD to a TV device was observed at follow-up, with need for antibradycardia pacing, ATP, or CRT being the main reasons. BMI >30 kg/m 2 and CKD predicted all-cause need for a TV device., (Copyright © 2022 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.)

In this work, we aim to identify sensitive neurophysiological biomarkers of axonal degeneration in CIDP patients. A total of 16 CIDP patients, fulfilling the clinical and neurophysiological criteria for typical CIDP, treated with subcutaneous immunoglobulin (ScIg) (0.4 g/kg/week) were evaluated at baseline (before ScIg treatment) and after long-term treatment with ScIg (24 months) by clinical assessment scales, nerve conduction studies (NCS) and electromyography (EMG). Conventional and non-conventional neurophysiological parameters: motor unit potential (MUP) analysis, MUP thickness and size index (SI)] and interference pattern (IP) features were evaluated after long-term treatment (24 months) and compared with a population of 16 healthy controls (HC). An increase of distal motor latency (DML) and reduced compound motor action potential (CMAP) amplitude and area in CIDP patients suggest axonal damage of motor fibers, together with a significant increase of MUP amplitude, duration and area. Analysis of non-conventional MUP parameters shows no difference for MUP thickness; however, in CIDP patients, SI is increased and IP area and amplitude values are lower than HC. Despite clinical and neurophysiological improvement after ScIg treatment, neurophysiological analysis revealed axonal degeneration of motor fibers and motor unit remodeling. Correlation analysis shows that the axonal degeneration process is related to the diagnostic and therapeutic delay. MUP area and SI parameters can detect early signs of axonal degeneration, and their introduction in clinical practice may help to identify patients with the worst outcome.

Cardiac amyloidosis (CA) manifests as infiltrative cardiomyopathy with a hypertrophic pattern, usually presenting with heart failure with a preserved ejection fraction. In addition, degenerative valvular heart disease, particularly severe aortic stenosis, is commonly seen in patients with CA. However, amyloid fibril deposition might also infiltrate the conduction system and promote the development of electrical disorders, including ventricular tachyarrhythmias, atrio-ventricular block or acute electromechanical dissociation. These manifestations can increase the risk of sudden cardiac death. This review summarises the pathophysiological mechanisms and risk factors for sudden cardiac death in CA and focuses on the major current concerns regarding medical and device management in this challenging scenario., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 The Author(s).

Introduction and Objectives: Our objective was to compare the rate of complications in thoracolumbar fractures that occurred during the early postoperative period in patients with multiple high-energy trauma according to the time of surgery. As a secondary objective, to estimate which variables were associated with surgery before 72 h., Material and Methods: Retrospective analysis of a series of patients with thoracolumbar fractures and multiple associated injuries in other anatomical regions due to high energy trauma. Surgically treated in an occupational trauma referral center, by the same surgical team and during the period between January 2013 and December 2019., Results: We analyzed a sample of 40 patients (39 men and 1 woman). The rate of complications was independent of surgical delay (before and after 72 h) (p = 0.827). There were statistically significant differences between early and later surgery groups in the variables age, systolic blood pressure, initial SOFA score and presence of neurological damage (p = 0.014; p = 0.029; p = 0.032; p = 0.012). The overall surgical delay was correlated with the SOFA score (p = 0.007)., Conclusion: The rate of early postoperative complications did not show significant differences between the early and late surgery groups. We observed that the patients who had been operated before 72 h from trauma were younger, had more association with neurological syntoms, presented higher blood pressure values and less physiological damage. Surgical delay was positively correlated with SOFA score on arrival., (Copyright © 2021 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.)

Background: It has been observed that the fourth-generation cryoballoon (CB4) ablation catheter increased the rate of acute real-time recordings of pulmonary vein isolation (PVI) during the ablation for the treatment of atrial fibrillation (AF). The aim of this analysis was to compare the long-term outcome results between patients treated with the CB4 and second-generation cryoballoon (CB2)., Methods: In total, 492 patients suffering from AF, underwent PVI ablation with either the CB2 or CB4 catheter within this examination of the 1STOP real-world Italian project and were included in the analysis. Specifically, 246 consecutive patients treated by CB4 were compared to 246 propensity-matched control patients who underwent PVI using CB2., Results: When comparing the patient cohorts treated with CB2 versus CB4, acute success rate (99.6 ± 4.7% vs. 99.7 ± 3.6%, p = .949) and peri-procedural complications (3.7% vs.1.2%, p = .080) were similar in both groups, respectively. However, procedure time (100 vs.75 min, p < .001) and fluoroscopy duration (21 vs.17 min, p < .001) were all significantly lower in the CB4 treated patient cohort. At the 12-month follow-up, the freedom from AF recurrence after a 90-day blanking period was significant higher in the CB4 as compared with the CB2 group (93.3% vs.81.3%, p < .001)., Conclusions: In summary, usage of the CB4 ablation catheter increased the rate of acute PVI recording capability and resulted in a higher rate of long-term PVI success, as demonstrated by the reduced rate of AF recurrence in comparison to the CB2 cohort at the 12-month follow-up period., (© 2022 Wiley Periodicals LLC.)

An anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus, with an interarterial course, has been associated with an increased risk of myocardial ischemia and sudden death. As the exact pathophysiology of AAOCA is not well understood, the clinical management is also not well defined. With increased use of non-invasive imaging, the diagnosis of AAOCA is increasing and the association of anomalous origin and atherosclerotic disease is becoming a more important topic. We report a rare case of AAOCA chronic total occlusion (CTO). A 40-year-old Caucasian man was referred for invasive coronary angiography (ICA) due to typical chest pain and positive myocardial scintigraphy. ICA demonstrated CTO of an anomalous right coronary artery (ARCA) originating from the left side of the ascending aorta with an interarterial course. There was no lesion in the left coronary artery. During the procedure, unexpected rupture of the coronary artery occurred after dilatation with a small balloon at low pressure. The complication in this case was handled with good procedural final result but was an occasion for a food for thought. Coronary artery perforations are rare but life-threatening procedural complications that are usually caused by predisposing anatomical and procedural factors. We issue a warning on the risk of complications during complex percutaneous coronary intervention of these arteries, and we reconsidered the pathophysiology of the anomaly in a way that could change the approach to the disease. Based on this complication, we hypothesized that the wall of the artery could be fragile due to histopathological alterations, which could have a role in the pathophysiology of coronary malignancy. Future autopsy studies should be focused on the analysis of the arterial wall of the patient affected by sudden death with this anomaly., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Cocco, Madonna, Cammalleri, Cocco, De Stefano, Ricciardi, Grigioni and Ussia.)

Background: A few limited case series have shown that the subcutaneous implantable cardioverter-defibrillator (S-ICD) system is safe for teenagers and young adults, but a large-scale analysis currently is lacking., Objectives: The purpose of this study was to compare mid-term device-associated outcomes in a large real-world cohort of S-ICD patients, stratified by age at implantation., Methods: Two propensity-matched cohorts of teenagers + young adults (≤30 years old) and adults (>30 years old) were retrieved from the ELISIR Registry. The primary outcome was the comparison of inappropriate shock rate. Complications, freedom from sustained ventricular arrhythmias, and overall and cardiovascular mortality were deemed secondary outcomes., Results: Teenagers + young adults represented 11.0% of the entire cohort. Two propensity-matched groups of 161 patients each were used for the analysis. Median follow-up was 23.1 (13.2-40.5) months. In total, 15.2% patients experienced inappropriate shocks, and 9.3% device-related complications were observed, with no age-related differences in inappropriate shocks (16.1% vs 14.3%; P = .642) and complication rates (9.9% vs 8.7%; P = .701). At univariate analysis, young age was not associated with increased rates of inappropriate shocks (hazard ratio [HR] 1.204 [0.675-2.148]: P = .529). At multivariate analysis, use of the SMART Pass algorithm was associated with a strong reduction in inappropriate shocks (adjusted HR 0.292 [0.161-0.525]; P <.001), whereas arrhythmogenic right ventricular cardiomyopathy (ARVC) was associated with higher rates of inappropriate shocks (adjusted HR 2.380 [1.205-4.697]; P = .012)., Conclusion: In a large multicenter registry of propensity-matched patients, use of the S-ICD in teenagers/young adults was safe and effective. The rates of inappropriate shocks and complications between cohorts were not significantly different. The only predictor of increased inappropriate shocks was a diagnosis of ARVC., (Copyright © 2022 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.)

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation technique that is increasingly used as a nonpharmacological intervention against cognitive impairment in Alzheimer's disease (AD) and other dementias. Although rTMS has been shown to modify cognitive performances and brain functional connectivity (FC) in many neurological and psychiatric diseases, there is still no evidence about the possible relationship between executive performances and resting-state brain FC following rTMS in patients with mild cognitive impairment (MCI). In this preliminary study, we aimed to evaluate the possible effects of rTMS of the bilateral dorsolateral prefrontal cortex (DLPFC) in 27 MCI patients randomly assigned to two groups: one group received high-frequency (10 Hz) rTMS (HF-rTMS) for four weeks ( n = 11), and the other received sham stimulation ( n = 16). Cognitive and psycho-behavior scores, based on the Repeatable Battery for the Assessment of Neuropsychological Status, Beck Depression Inventory-II, Beck Anxiety Inventory, Apathy Evaluation Scale, and brain FC, evaluated by independent component analysis of resting state functional MRI (RS-fMRI) networks, together with the assessment of regional atrophy measures, evaluated by whole-brain voxel-based morphometry (VBM), were measured at baseline, after five weeks, and six months after rTMS stimulation. Our results showed significantly increased semantic fluency ( p = 0.026) and visuo-spatial ( p = 0.014) performances and increased FC within the salience network ( p ≤ 0.05, cluster-level corrected) at the short-term timepoint, and increased FC within the left fronto-parietal network ( p ≤ 0.05, cluster-level corrected) at the long-term timepoint, in the treated group but not in the sham group. Conversely, regional atrophy measures did not show significant longitudinal changes between the two groups across six months. Our preliminary findings suggest that targeting DLPFC by rTMS application may lead to a significant long-term increase in FC in MCI patients in a RS network associated with executive functions, and this process might counteract the progressive cortical dysfunction affecting this domain.

Background: To date, only a few comparisons between subcutaneous implantable cardioverter-defibrillator (S-ICD) patients undergoing and those not undergoing defibrillation testing (DT) at implantation (DT+ vs DT-) have been reported., Objective: The purpose of this study was to compare long-term clinical outcomes of 2 propensity-matched cohorts of DT+ and DT- patients., Methods: Among consecutive S-ICD patients implanted across 17 centers from January 2015 to October 2020, DT- patients were 1:1 propensity-matched for baseline characteristics with DT+ patients. The primary outcome was a composite of ineffective shocks and cardiovascular mortality. Appropriate and inappropriate shock rates were deemed secondary outcomes., Results: Among 1290 patients, a total of 566 propensity-matched patients (283 DT+; 283 DT-) served as study population. Over median follow-up of 25.3 months, no significant differences in primary outcome event rates were found (10 DT+ vs 14 DT-; P = .404) as well as for ineffective shocks (5 DT- vs 3 DT+; P = .725). At multivariable Cox regression analysis, DT performance was associated with a reduction of neither the primary combined outcome nor ineffective shocks at follow-up. A high PRAETORIAN score was positively associated with both the primary outcome (hazard ratio 3.976; confidence interval 1.339-11.802; P = .013) and ineffective shocks alone at follow-up (hazard ratio 19.030; confidence interval 4.752-76.203; P = .003)., Conclusion: In 2 cohorts of strictly propensity-matched patients, DT performance was not associated with significant differences in cardiovascular mortality and ineffective shocks. The PRAETORIAN score is capable of correctly identifying a large percentage of patients at risk for ineffective shock conversion in both cohorts., (Copyright © 2021 Heart Rhythm Society.

COVID-19 pandemic has induced an urgent reorganization of the healthcare system to ensure continuity of care for patients affected by chronic neurological diseases including myasthenia gravis (MG). Due to the fluctuating nature of the disease, early detection of disease worsening, adverse events, and possibly life-threatening complications is mandatory. This work analyzes the main unresolved issues in the management of the myasthenic patient, the possibilities offered so far by digital technologies, and proposes an online evaluation protocol based on 4 simple tests to improve MG management. Telemedicine and Digital Technology might help neurologists in the clinical decision-making process of MG management, avoiding unnecessary in presence consultations and allowing a rational use of the time and space reduced by the pandemic., (© 2021.

Background: Recently, the Food and Drug Administration issued a recall for the subcutaneous implantable cardioverter-defibrillator (S-ICD) because of the possibility of lead ruptures and accelerated battery depletion., Objective: The aim of this study was to evaluate device-related complications over time in a large real-world multicenter S-ICD cohort., Methods: Patients implanted with an S-ICD from January 2015 to June 2020 were enrolled from a 19-institution European registry (Experience from the Long-term Italian S-ICD registry [ELISIR]; ClinicalTrials.gov identifier NCT0473876). Device-related complication rates over follow-up were collected. Last follow-up of patients was performed after the Boston Scientific recall issue., Results: A total of 1254 patients (median age 52.0 [interquartile range 41.0-62.2] years; 973 (77.6%) men; 387 (30.9%) ischemic) was enrolled. Over a follow-up of 23.2 (12.8-37.8) months, complications were observed in 117 patients (9.3%) for a total of 127 device-related complications (23.6% managed conservatively and 76.4% required reintervention). Twenty-seven patients (2.2%) had unanticipated generator replacement after 3.6 (3.3-3.9) years, while 4 (0.3%) had lead rupture. Body mass index (hazard ratio [HR] 1.063 [95% confidence interval 1.028-1.100]; P < .001), chronic kidney disease (HR 1.960 [1.191-3.225]; P = .008), and oral anticoagulation (HR 1.437 [1.010-2.045]; P = .043) were associated with an increase in overall complications, whereas older age (HR 0.980 [0.967-0.994]; P = .007) and procedure performed in high-volume centers (HR 0.463 [0.300-0.715]; P = .001) were protective factors., Conclusion: The overall complication rate over 23.2 months of follow-up in a multicenter S-ICD cohort was 9.3%. Early unanticipated device battery depletions occurred in 2.2% of patients, while lead fracture was observed in 0.3%, which is in line with the expected rates reported by Boston Scientific., (Copyright © 2021 Heart Rhythm Society.

Introduction: Parkinson's disease (PD) is a neurodegenerative pathology characterized by motor and non-motor symptoms that often lead to several impairments. Many studies show the efficacy of different rehabilitation protocols aimed to improve balance and gait functions in PD patients. However, multiple factors may influence rehabilitation outcome. Recently, it has been observed as the cognitive reserve (CR) may influence the rehabilitation outcome, helping to address the patient toward technological or conventional rehabilitation. Our study investigated how CR may affect motor rehabilitation outcomes in PD patients who undergo virtual reality (VR) rehabilitation, aimed at improving walking and balance., Materials and Methods: Thirty patients affected by idiopathic PD were enrolled. Patients underwent 12 sessions VR training, over 6 weeks (45 min). Six-Minute Walk Test (6MWT) and Berg Balance Scale (BBS) were used to assess walking and balance, respectively. CR was assessed by Cognitive Reserve Index questionnaire (CRIq)., Results: Significant correlations between CR and change from baseline in walking and balance measures were found, with a significant positive correlation between CRIq and 6MWT (r=0.50, p=0.01) and between CRIq and BBS (r=0.41, p=0.04)., Discussion: Our results showed that PD patients with higher CR treated with VR improved significantly more in their balance and walking distance than those with lower CR. The current study suggests that VR when aimed to improve balance and walking in PD patients is more effective in patients with higher CR., (© 2021. Fondazione Società Italiana di Neurologia.)

Emerging evidence suggests that memory deficit in amyotrophic lateral sclerosis (ALS), a neurodegenerative disease with varying impairment of motor abilities and cognitive profile, may be independent from executive dysfunction. Our multimodal magnetic resonance imaging (MRI) approach, including resting state functional MRI (RS-fMRI), diffusion tensor imaging (DTI) and voxel-based morphometry (VBM), aimed to investigate structural and functional changes within and beyond the Papez circuit in non-demented ALS patients (n = 32) compared with healthy controls (HCs, n = 21), and whether these changes correlated with neuropsychological measures of verbal and non-verbal memory. We revealed a decreased functional connectivity between bilateral hippocampus, bilateral parahippocampal gyri and cerebellum in ALS patients compared with HCs. Between-group comparisons revealed white matter abnormalities in the genu and body of the corpus callosum and bilateral cortico-spinal tracts, superior longitudinal and uncinate fasciculi in ALS patients (p < .05, family-wise error corrected). Interestingly, changes of Digit Span forward performance were inversely related to RS-fMRI signal fluctuations in the cerebellum, while changes of both episodic and visual memory scores were inversely related to mean and radial diffusivity abnormalities in several WM fiber tracts, including middle cerebellar peduncles. Our findings revealed that ALS patients showed significant functional and structural connectivity changes across the regions comprising the Papez circuit, as well as more extended areas including cerebellum and frontal, temporal and parietal areas, supporting the theory of a multi-system pathology in ALS that spreads from cortical to subcortical structures., (© 2020.

Aims: Peripheral neuropathy (PN) affects two-thirds of type 2 diabetes patients (T2DM). According to diabetic PN length-dependent pattern, neurophysiological evaluation of foot-sole nerves might increase NCS diagnostic sensitivity, hence allowing early diagnosis of PN. Thus, we aim to assess the ability of whole plantar nerve (WPN) conduction in diabetic PN early diagnosis., Methods: This is a single center prospective observational cohort study on 70 T2DM patients referred to Internal Medicine Unit of A.O.U. "Luigi Vanvitelli" between October 2019/October 2020. Primary endpoint was WPN efficacy assessment in PN early detection. As secondary, we evaluated (i) a potential cut-off of SNAPs amplitude by WPN and (ii) WPN diagnostic accuracy vs. gold-standard distal sural nerve conduction., Results: ROC curve analysis allowed to establish two potential cut-offs for people aged ≤60 years (AUROC: 0.83, 95%CI: 0.69-0.96, p < 0.001) and ≤60 years (AUROC: 0.76, 95%CI: 0.59-0.93, p = 0.017). In depth, we fixed a cut-off of WPN-SNAP amplitude of 4.55 μV and 2.65 μV, respectively, with subsequent 48 patients classified as PN-T2DM., Conclusions: Our data support WPN conduction study reliability in characterizing the most distal sensory nerve fibers at lower limbs. Thus, WPN may represent an extremely useful diagnostic tool for diabetic PN early detection., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

Objective: Advanced neuroimaging techniques may offer the potential to monitor disease progression in amyotrophic lateral sclerosis (ALS), a neurodegenerative, multisystem disease that still lacks therapeutic outcome measures. We aim to investigate longitudinal functional and structural magnetic resonance imaging (MRI) changes in a cohort of patients with ALS monitored for one year after diagnosis., Methods: Resting state functional MRI, diffusion tensor imaging (DTI), and voxel-based morphometry analyses were performed in 22 patients with ALS examined by six-monthly MRI scans over one year., Results: During the follow-up period, patients with ALS showed reduced functional connectivity only in some extramotor areas, such as the middle temporal gyrus in the left frontoparietal network after six months and in the left middle frontal gyrus in the default mode network after one year without showing longitudinal changes of cognitive functions. Moreover, after six months, we reported in the ALS group a decreased fractional anisotropy (P = .003, Bonferroni corrected) in the right uncinate fasciculus. Conversely, we did not reveal significant longitudinal changes of functional connectivity in the sensorimotor network, as well as of gray matter (GM) atrophy or of DTI metrics in motor areas, although clinical measures of motor disability showed significant decline throughout the three time points., Conclusion: Our findings highlighted that progressive impairment of extramotor frontotemporal networks may precede the appearance of executive and language dysfunctions and GM changes in ALS. Functional connectivity changes in cognitive resting state networks might represent candidate radiological markers of disease progression.

Objectives: To investigate caregivers and patients characteristics related to different dimensions of burden in Parkinson's disease (PD)., Methods: 55 pairs of PD patients and caregivers were recruited. The burden was evaluated with the Caregiver Burden Inventory (CBI). Multivariate analysis was applied to evaluate the impact of caregivers' and patients' characteristics on the varying aspects of burden., Results: ADL score was the dominant predictor for the total score and all dimensions of CBI, except for the social burden, which is strongly predicted by the motor severity of PD. As one can easily imagine, the Total CBI decreases as the ADL score increases., Discussion: An increased appreciation for characteristics of caregiver burden is a fundamental aspect of the patient's global evaluation. Clinicians may need to directly probe for these factors in the caregiver as they may not be elicited routinely.

Background: Multiple left ventricular pacing strategies have been suggested for improving response to cardiac resynchronization therapy (CRT). However, these programming strategies may sometimes entail accepting configurations with high pacing threshold and accelerated battery drain. We assessed the feasibility of predefined pacing programming protocols, and we evaluated their impact on device longevity and their cost-impact., Methods: We estimated battery longevity in 167 CRT-D patients based on measured pacing parameters according to multiple alternative programming strategies: single-site pacing associated with lowest threshold, non-apical location, longest interventricular delay, and pacing from two electrodes. To determine the economic impact of each programming strategy, we applied the results of a model-based cost analysis using a 15-year time horizon., Results: Selecting the electrode with the lowest threshold resulted in a median device longevity of 11.5 years. Non-apical pacing and interventricular delay maximization were feasible in most patients and were obtained at the price of a few months of battery life. Device longevity of > 10 years was preserved in 87% of cases of non-apical pacing and in 77% on pacing at the longest interventricular delay. The mean reduction in battery life when the second electrode was activated was 1.5 years. Single-site pacing strategies increased the therapy cost by 4-6%, and multi-site pacing by 12-13%, in comparison with the lowest-cost scenario., Conclusions: Modern CRT-D systems ensure effective pacing and allow multiple optimization strategies for maximizing service life or for enhancing effectiveness. Single- or multi-site pacing strategies can be implemented without compromising device service life and at an acceptable increase in therapy cost.

Background: Current guidelines recommend defibrillation testing (DT) performance in patients with a subcutaneous implantable cardioverter defibrillator (S-ICD), theoretically to reduce the amount of ineffective shocks. DT, however, has been proven unnecessary in transvenous ICD and real-world data show a growing trend in avoidance of DT after S-ICD implantation., Methods: All patients undergoing S-ICD implant at nine associated Italian centers joining in the ELISIR registry (ClinicalTrials.gov Identifier: NCT04373876) were enrolled and classified upon DT performance. Long-term follow-up events were recorded and compared to report the long-term efficacy and safety of S-ICD implantations without DT in a real-world setting., Results: A total of 420 patients (54.0 ± 15.5 years, 80.0% male) were enrolled in the study. A DT was performed in 254 (60.5%) patients (DT+ group), while in 166 (39.5%) was avoided (DT- group). Over a median follow-up of 19 (11-31) months, a very low rate (0.7%) of ineffective shocks was observed, and no significant differences in the primary combined arrhythmic outcome were observed between the two groups (p = .656). At regression analysis, the only clinical predictor associated with the primary combined outcome was S-ICD placement for primary prevention (odds ratio: 0.42; p = .013); DT performance instead was not associated with a reduction in primary outcome (p = .375)., Conclusion: Implanting an S-ICD without DT does not appear to impact the safety of defibrillation therapy and overall patients' survival., (© 2020 Wiley Periodicals LLC.)

Background: Testicular adrenal rest tumors (TARTs) are benign neoplasms affecting patients with congenital adrenal hyperplasia (CAH). The prevalence of TART in adult patients with CAH is not well known. Ultrasonography (US) is the main tool for diagnosing TART and the role of contrast-enhanced US (CEUS) is never investigated. The aim of this study was to evaluate the TART prevalence in adults with CAH, by stratifying patients according to disease phenotype and assessing the diagnostic performance of US, color Doppler (CD) US and CEUS., Methods: Male patients >16 years old with certain diagnosis of CAH who underwent US for TARTs, between December 2015 and September 2019 were prospectively enrolled. The control group included patients without CAH affected by testicular lesions at US other than TARTs., Results: TARTs were identified in 16 of 52 patients (31%), of whom 15 (93.8%) displayed the salt-wasting (SW) form (P<0.001). The prevalence of TARTs in patients with the SW form was 54%. One patient with the non-classic (NC) form (6%) showed TART (likely the first documented case). The mean age of patients upon detection of TARTs was significantly younger compared with the control group (P<0.001); moreover, TARTs were bilateral in 15/16 patients (93.8%; P<0.001) and the largest lesion was more frequent in the medium third of testis in the TART group (87.5%), statistically different from the control group (P=0.013)., Conclusions: TARTs almost exclusively affected patients with the SW form of CAH. Age at diagnosis and bilateralism are useful factors for achieving a correct diagnosis of TARTs in CAH adult patients., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tau-20-998).

Objective: Advanced neuroimaging techniques may offer the potential to monitor disease spreading in amyotrophic lateral sclerosis (ALS). We aim to investigate brain functional and structural magnetic resonance imaging (MRI) changes in a cohort of ALS patients, examined at diagnosis and clinically monitored over 18 months, in order to early discriminate fast progressors (FPs) from slow progressors (SPs). Methods: Resting state functional MRI (RS-fMRI), diffusion tensor imaging (DTI) and voxel-based morphometry (VBM) analyses were performed at baseline in 54 patients with ALS and 22 HCs. ALS patients were classified a posteriori into FPs ( n  = 25) and SPs ( n  = 29) based on changes in Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score from baseline to the 18-month assessment (ΔALSFRS-R), applying a k-means clustering algorithm. Results: At diagnosis, when compared to HCs, ALS patients showed reduced functional connectivity in both motor and extra-motor networks. When compared to SPs, at baseline, FPs showed decreased function connectivity in paracentral lobule (sensorimotor network), precuneus (in the default mode network), middle frontal gyri (frontoparietal networks) and increased functional connectivity in insular cortices (salience network). Structural analyses did not reveal significant differences in gray and white matter damage by comparing FPs to SPs. Receiver operating characteristic (ROC) curve analysis showed that functional connectivity increase in the left insula at baseline best discriminated FPs and SPs (area under the curve 78%). Conclusions: Impairment of extra-motor networks may appear early in ALS patients with faster disease progression, suggesting that a more widespread functional connectivity damage may be an indicator of poorer prognosis.

Telerehabilitation is defined as a set of tools, procedures, and protocols to deliver rehabilitation programs remotely. It involves the use of various communication technologies to efficiently provide rehabilitation services distantly or via some other remote environment. After an orthopedic procedure, physical rehabilitation is essential to restore joint's function, to improve quality of life as well as to relieve pain, to recovery independence. The effectiveness of telerehabilitation has been studied in literature. The aim of this narrative review is to update the current evidence, evaluate the efficacy of telerehabilitation after hip, and knee prosthesis surgery for end stage arthrosis. Results show that it is useful to integrate traditional interventions with telerehabilitation to accelerate efficiency in existing healthcare delivery systems. Future high-methodological-quality studies should be conducted to evaluate the long-term efficacy and safety of innovative technologies., (Copyright 2020 Biolife Sas. www.biolifesas.org.)

Background: Safinamide, as a levodopa adjunct, is effective in reducing motor fluctuations in Parkinson's disease (PD) patients; however, scarce evidence is available regarding its use in older PD patients., Aim: To evaluate the safety and tolerability of safinamide as an adjunct therapy in patients aged ≥ 60 years with advanced PD., Methods: A retrospective study including 203 PD patients admitted to a geriatric day hospital, who were evaluated following an extensive clinical protocol. Safinamide use was categorized as never used, ongoing, and withdrawn. Potential correlations of Safinamide withdrawal were investigated in stepwise backward logistic regression models., Results: A total of 44 out of 203 participants were current or former users of Safinamide. Overall, 14 (32%) patients discontinued due to treatment-emergent adverse events (TEAEs). Withdrawal was not associated with older age., Conclusions: Safinamide as an adjunct therapy in patients aged ≥ 60 years with advanced PD was found to be safe and well-tolerated in older patients. There were no specific demographic or clinical characteristics associated with suspension.

Besides the prominent motor syndrome, some patients affected by amyotrophic lateral sclerosis (ALS) complain of many non-motor symptoms during the disease course, in particular chronic pain that significantly reduces the patients' quality of life. Complex regional pain syndrome (CRPS) is a rare painful condition, rarely described in ALS patients. We present the clinical case of a patient affected by spinal-onset ALS, who developed a type I CRPS (CRPS-I) at the upper limbs. To the best of our knowledge, only five cases of ALS-CRPS-I have been reported and they share some peculiar features: ALS spinal-onset with classic phenotype, rapid deterioration of quality of life, and a poor prognosis. Different mechanisms have been supposed in the pathogenesis of both CRPS and ALS, resulting in distinctive clinical presentations. Altered plasticity of brain sensory and motor areas might represent a common feature that seems to influence negatively ALS progression and prognosis.

Introduction: Early evidence suggests that multipoint left ventricular pacing (MPP) may improve response to cardiac resynchronization therapy (CRT). It is unknown whether this benefit is sustained and cost-effective. We used real-world data to evaluate long-term impact of MPP-ON clinical status, heart failure hospitalizations (HFH) and costs., Methods: The Italian registry on multipoint left ventricular pacing is a prospective, multicenter registry of patients implanted with MPP-enabled CRT devices. For this analysis, clinical and echocardiographic data were collected through 24 months and compared between patients with (MPP-ON) or without (MPP-OFF) early MPP activation at implant. The total cost of each HFH was estimated with national Italian reimbursement rates., Results: The study included 190 MPP-OFF and 128 MPP-ON patients with similar baseline characteristics. At 1 and 2 years, the MPP-ON group had lower rates of HFH vs MPP-OFF (1-year hazard ratio [HR]: 0.14, P = .0014; 2-year HR: 0.38, P = .009). The finding persisted in a subgroup of patients with consistent MPP activation through follow-up (1-year HR: 0.19; P = .0061; 2-year HR: 0.39, P = .022). Total HFH per-patient costs were lower in the MPP-ON vs the MPP-OFF group at 1 year (€101 ± 50 vs €698 ± 195, P < .001) and 2 years (€366 ± 149 vs €801 ± 203, P = .038). More MPP-ON patients had ≥5% improvement in ejection fraction (76.8% vs 65.4%, P = .025) and clinical composite score (66.7% vs 47.5%, P = .01)., Conclusions: In this multicenter clinical study, early MPP activation was associated with a significant reduction in cumulative HFH and related costs after 1 and 2 years of follow-up., (© 2020 Wiley Periodicals, Inc.)

Introduction: Use of non-vitamin K oral anticoagulants (NOACs) has rapidly increased worldwide. We aimed to systematically assess the available evidence regarding the safety and efficacy of NOACs in patients undergoing cardiac implantable electronic device (CIED) surgery., Methods: We performed a systematic literature search. Eligible randomised controlled trials and cohort studies were included. The primary outcome measures were clinically significant device-pocket haematoma and thromboembolic events., Results: A total of 12 studies were included, equating to 2120 patients. The separate pooling of rate of events showed a low incidence of clinically significant device-pocket haematoma, although numerically higher in patients on continued (1.5%; CI 95% 0.8-3.0) versus interrupted NOAC (0.9%; CI 95% 0.5-1.7). The rate of any device-pocket haematoma was numerically higher in the continued versus interrupted NOAC group (5.4%; CI 95% 3.8-7.7 versus 2.4%; CI 95% 1.8-3.3). The incidence of thromboembolic events (0.4%; CI 95% 0.2-0.8) was low and comparable. From a meta-analysis of 3 studies (equating to 773 subjects) allowing for a comparison of continued versus interrupted NOAC, we found no significant difference between the 2 strategies in terms of clinically significant pocket haematoma (RR1.14; CI 95% 0.43-3.06, p = 0.79), thromboembolic complications (RR1.03; CI 95% 0.06-16.37, p = 0.98), and any pocket haematoma (RR1.19; CI 95% 0.65-2.20, p = 0.57)., Conclusion: Use of NOACs at the time of CIEDs surgery appears to be safe, and either strategy of peri-procedure continuation or interruption might be reasonable. However, continuation of NOAC seems to be associated with a numerically higher rate of bleeding complications. Certainty of the evidence is low, and further studies are required to confirm these findings., (Copyright © 2020 Elsevier Ltd. All rights reserved.)
