    Abstract Zinc oxide (ZnO) nanostructures are widely applied materials, and are also capable of antimicrobial action. They can be obtained by several methods, which include physical and chemical approaches. Considering the recent rise of green and low-cost synthetic routes for nanomaterial development, electrochemical techniques represent a valid alternative to biogenic synthesis. Following a hybrid electrochemical-thermal method modified by our group, here we report on the aqueous electrosynthesis of ZnO nanomaterials based on the use of alternative stabilizers. We tested both benzyl-hexadecyl-dimetylammonium chloride (BAC) and poly-diallyl-(dimethylammonium) chloride (PDDA). Transmission electron microscopy images showed the formation of rod-like and flower-like structures with a variable aspect-ratio. The combination of UV-Vis, FTIR and XPS spectroscopies allowed for the univocal assessment of the material composition as a function of different thermal treatments. In fact, the latter guaranteed the complete conversion of the as-prepared colloidal materials into stoichiometric ZnO species without excessive morphological modification. The antimicrobial efficacy of both materials was tested against

    Abstract Objective: To investigate the electroclinical characteristics and the prognostic impact of generalized fast discharges in a large cohort of genetic generalized epilepsy (GGE) patients studied with 24-h prolonged ambulatory electroencephalography (paEEG).
    Methods: This retrospective multicenter cohort study included 202 GGE patients. The occurrence of generalized paroxysmal fast activity (GPFA) and generalized polyspike train (GPT) was reviewed. GGE patients were classified as having idiopathic generalized epilepsy (IGE) or another GGE syndrome (namely perioral myoclonia with absences, eyelid myoclonia with absences, epilepsy with myoclonic absences, generalized epilepsy with febrile seizures plus, or GGE without a specific epilepsy syndrome) according to recent classification proposals.
    Results: GPFA/GPT was found in overall 25 (12.4%) patients, though it was significantly less frequent in IGE compared with other GGE syndromes (9.3 vs. 25%,
    Conclusion: We found that generalized fast discharges were more common than expected in GGE patients when considering the entire GGE spectrum. In addition, our study highlighted that GPFA/GPT could be found along the entire GGE continuum, though their occurrence was more common in less benign GGE syndromes. Finally, we confirmed that GPFA/GPT was associated with difficult-to-treat GGE, as evidenced by the multivariable analysis and the higher ASM load during history.

    Abstract Introduction: Dysregulation of cerebral glucose consumption, alterations in cerebrospinal fluid (CSF) biomarkers, and cognitive impairment have been reported in patients with obstructive sleep apnoea (OSA). On these bases, OSA has been considered a risk factor for Alzheimer's disease (AD). This study aimed to measure cognitive performance, CSF biomarkers, and cerebral glucose consumption in OSA patients and to evaluate the effects of continuous positive airway pressure (CPAP) treatment on these biomarkers over a 12-month period.
    Methods: Thirty-four OSA patients and 34 controls underwent
    Results: Significantly reduced glucose consumption was observed in the bilateral praecuneus, posterior cingulate cortex, and frontal areas in OSA patients than controls. At baseline, OSA patients also showed lower β-amyloid
    Conclusions: Cognitive impairment, reduced cerebral glucose consumption, and alterations in CSF biomarkers were observed in OSA patients, which may reinforce the hypothesis of AD neurodegenerative processes triggered by OSA. Notably, cognition and brain glucose consumption improved after beneficial CPAP treatment. Further studies are needed to evaluate the long-term effects of CPAP treatment on these AD biomarkers.

    Abstract Objective: The aim of our study was to evaluate the diagnostic and prognostic value of Electroencephalogram (EEG), brain Magnetic Resonance Imaging (MRI) and cerebrospinal fluid features, currently representing Creutzfeldt-Jacob Disease (CJD) diagnostic criteria.
    Methods: A retrospective study on rapidly progressive dementia patients admitted at the Neurology Clinic of the University of Rome "Tor Vergata" between 2015 and 2020 was conducted. We evaluated clinical, EEG, cerebrospinal fluid and neuroradiological findings.
    Results: Our analysis included 13 patients with probable CJD and 18 patients with non-CJD rapidly progressive dementia. Periodic sharp wave complexes were observed in 7/13 CJD and in 4/18 non-CJD patients (p =.151). The sub-analysis according to the EEG features revealed that CJD patients with earlier periodic sharp wave complexes had a significantly lower average survival time (p =.003), a shorter time to admission (p =.003) and lower levels of cerebrospinal fluid p-tau (p =.008) compared to CJD patients without periodic sharp wave complexes. Finally, they did not show signs of signal alteration on Fluid Attenuated Inversion Recovery images.
    Conclusions: Despite the lowest diagnostic specificity and sensibility among the CJD criteria, periodic sharp wave complexes could identify a distinctive phenotype hallmarked by a faster evolution, a reduced survival time and specific MRI and cerebrospinal fluid features.
    Significance: The early presence of the typical EEG pattern may play a prognostic role in CJD.

    Abstract Objective: Epilepsy treatment during pregnancy is still challenging. The study is aimed at comparing the efficacy and safety of carbamazepine (CBZ), lamotrigine (LTG) and levetiracetam (LEV) monotherapies during pregnancy in women with focal (FE) or generalized (GE) epilepsy.
    Methods: A multicentre retrospective study was conducted to evaluate seizures frequency and seizure freedom (SF) rate during 3 months before pregnancy, each trimester of gestation and post-partum period in women on monotherapy with CBZ, LTG and LEV.
    Results: Fifty-seven pregnancies (45 FE, 12 GE) on monotherapy (29 CBZ, 11 LTG, 17 LEV) were included. A significant reduction of seizure frequency was found in the first trimester of pregnancy as compared with that one before pregnancy (p = 0.004), more evident in GE (p = 0.003) and in LEV group (p = 0.004). The SF rate significantly increased in the first trimester in comparison to that one before pregnancy and persisted in the post-partum period in the whole sample (p < 0.001) and in women on LEV (p = 0.004). Besides, 88.57% of SF women before pregnancy remained unchanged during gestation and the post-partum period. One major heart malformation in CBZ and no major malformations in LTG and LEV groups were found.
    Conclusions: A better clinical outcome during pregnancy emerged since the first trimester in comparison to the before-pregnancy period, mostly evident in women with GE and LEV therapy, reinforcing the hypothesis of a protective role of pregnancy versus seizures. SF before pregnancy represents a significant predictive factor of good clinical outcome during gestation and the post-partum period. Compared to CBZ, LTG and LEV showed a better safety profile.

    Abstract Objectives: Epilepsy management in elderly patients is often complex because of several concomitant comorbidities that may limit the use of some antiepileptic drugs (AEDs). Levetiracetam (LEV) is a second-generation AED widely used in elderly patients with epilepsy while lacosamide (LCM), which has been recently approved in European Union (EU) as monotherapy for the treatment of focal onset seizures, is affected by a scarcity of data in such frail population. This study is aimed at assessing the efficacy and the tolerability of LCM as monotherapy in elderly patients affected by focal onset epilepsy compared with those receiving LEV.
    Methods: A retrospective chart review of patients aged ≥65 years suffering from focal onset seizures, with or without secondary generalization on LCM monotherapy or LEV monotherapy, was performed. Data regarding demographic characteristics, seizure type and etiology, LCM and LEV daily dose, number of lifetime AEDs, seizure frequency at baseline and at 12 months of follow-up, and seizure freedom rates were reported.
    Results: In this observational retrospective study, 22 patients on LCM (10 males, 12 females, mean age: 76.23 ± 7.5) and 24 patients on LEV (10 males, 14 females, mean age: 73.58 ± 6.39) were enrolled. Mean LCM daily dose was 204.51 ± 88.51 mg and mean LEV daily dose was 1281.25 ± 378.15 mg. All patients had comorbidities on chronic treatment. At 12 months of follow-up, mean monthly seizure frequency reduced from 4.23 ± 8.53 to 0.33 ± 0.9 (p < .001) in LCM group and from 2.29 ± 6.11 to 0.2 ± 0.81 (p < .001) in LEV group. Furthermore, 16/22 (72.7%) LCM patients were seizure-free at 12 months of follow-up while seizure freedom was achieved by 17/24 (70.8%) patients in LEV group.
    Discussion and conclusion: Epilepsy management in elderly patients is often challenging. In this retrospective real-life study, the efficacy and the tolerability of LCM as monotherapy was favorable even at low doses in older patients and comparable with LEV with a high rate of long-term seizure freedom. Considering the frequent comorbidities and the risk of drug-drug interactions, LCM monotherapy may be a valuable option in elderly patients with focal onset epilepsy because of its favorable pharmacokinetic profile.

    Abstract Perampanel (PER) is a third generation antiepileptic drug (AED), recently approved as add-on therapy in both focal and generalized seizures. Levetiracetam (LEV) is a second generation AED, widely used in patients with epilepsy because of its favorable safety and efficacy profiles. Perampanel and LEV treatments have been associated with the occurrence of similar adverse events (AEs) (sleepiness, irritability, depression, anxiety, aggressiveness). The aim of the present retrospective single center study was to verify the efficacy and tolerability of PER and LEV used as first add-on therapy in patients with epilepsy affected by secondarily generalized seizures. We collected data from 15 patients treated with PER and 26 patients treated with LEV and followed at our site with follow-up visits at 3, 6, and 12months. This retrospective study documented the comparable efficacy of PER and LEV as first add-on treatments in patients affected by uncontrolled secondarily generalized seizures. However, more patients withdrawn LEV because of AEs compared with PER at the 3- and 12-month follow-up visits. The better tolerability of PER observed in this study could be related to the low therapeutic dose of PER prescribed when it is used as first adjunctive treatment for better controlling secondarily generalized seizures.
