Abstract
PURPOSE According to preclinical evidence, GLP-1 receptor may be an actionable target in neurodegenerative disorders, including Alzheimer's disease (AD). Previous clinical trials of GLP-1 receptor agonists were conducted in patients with early AD, yielding mixed results. The aim was to assess in a proof-of-concept study whether slow-release exenatide, a long-acting GLP-1 agonist, can benefit the cognitive performance of people with mild cognitive impairment (MCI). METHODS Thirty-two (16 females) patients were randomized to either slow-release exenatide (n = 17; 2 mg s.c. once a week) or no treatment (n = 15) for 32 weeks. The primary endpoint was the change in ADAS-Cog11 cognitive test score at 32 weeks vs baseline. Secondary endpoints herein reported included additional cognitive tests and plasma readouts of GLP-1 receptor engagement. Statistical analysis was conducted by intention to treat. RESULTS No significant between-group effects of exenatide on ADAS-Cog11 score (p = 0.17) were detected. A gender interaction with treatment was observed (p = 0.04), due to worsening of the ADAS-Cog11 score in women randomized to exenatide (p = 0.018), after correction for age, scholar level, dysglycemia, and ADAS-Cog score baseline value. Fasting plasma glucose (p = 0.02) and body weight (p = 0.03) decreased in patients randomized to exenatide. CONCLUSION In patients with MCI, a 32-week trial with slow-release exenatide had no beneficial effect on cognitive performance. TRIAL REGISTRATION NUMBER NCT03881371, registered on 21 July, 2016.

Abstract
INTRODUCTION Visual rating scales are increasingly utilized in clinical practice to assess atrophy in crucial brain regions among patients with cognitive disorders. However, their capacity to predict Alzheimer's disease (AD)-related pathology remains unexplored, particularly within a heterogeneous memory clinic population. This study aims to assess the accuracy of a novel visual rating assessment, the antero-posterior index (API) scale, in predicting amyloid-PET status. Furthermore, the study seeks to determine the optimal cohort-based cutoffs for the medial temporal atrophy (MTA) and parietal atrophy (PA) scales and to integrate the main visual rating scores into a predictive model. METHODS We conducted a retrospective analysis of brain MRI and high-resolution TC scans from 153 patients with cognitive disorders who had undergone amyloid-PET assessments due to suspected AD pathology in a real-world memory clinic setting. RESULTS The API scale (cutoff ≥1) exhibited the highest accuracy (AUC = 0.721) among the visual rating scales. The combination of the cohort-based MTA and PA threshold with the API yielded favorable accuracy (AUC = 0.787). Analyzing a cohort of MCI/Mild dementia patients below 75 years of age, the API scale and the predictive model improved their accuracy (AUC = 0.741 and 0.813, respectively), achieving excellent results in the early-onset population (AUC = 0.857 and 0.949, respectively). CONCLUSION Our study emphasizes the significance of visual rating scales in predicting amyloid-PET positivity within a real-world memory clinic. Implementing the novel API scale, alongside our cohort-based MTA and PA thresholds, has the potential to substantially enhance diagnostic accuracy.

Abstract
Introduction. An easily accessible and inexpensive neurophysiological technique such as conventional electroencephalography may provide an accurate and generally applicable biomarker capable of differentiating dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) and Parkinson's disease-associated dementia (PDD). Method. We carried out a retrospective visual analysis of resting-state electroencephalography (EEG) recording of 22 patients with a clinical diagnosis of 19 probable and 3 possible DLB, 22 patients with probable AD and 21 with PDD, matched for age, duration, and severity of cognitive impairment. Results. By using the grand total EEG scoring method, the total score and generalized rhythmic delta activity frontally predominant (GRDAfp) alone or, even better, coupled with a slowing of frequency of background activity (FBA) and its reduced reactivity differentiated DLB from AD at an individual level with an high accuracy similar to that obtained with quantitative EEG (qEEG). GRDAfp alone could also differentiate DLB from PDD with a similar level of diagnostic accuracy. AD differed from PDD only for a slowing of FBA. The duration and severity of cognitive impairment did not differ between DLB patients with and without GRDAfp, indicating that this abnormal EEG pattern should not be regarded as a disease progression marker. Conclusions. The findings of this investigation revalorize the role of conventional EEG in the diagnostic workup of degenerative dementias suggesting the potential inclusion of GRDAfp alone or better coupled with the slowing of FBA and its reduced reactivity, in the list of supportive diagnostic biomarkers of DLB.

Abstract
BACKGROUND Although FD may affect up to 10% of the general population, the therapy for FD is not standard. Recently, ginger-based food supplements have been proposed in order to restore FD symptoms. Our aim was to assess the efficacy of a new nutraceutical formulation containing extract of gingerol and thymus as a possible natural treatment in managing the symptoms of functional dyspepsia (FD). METHODS We retrospectively analyzed the efficacy and safety profiles of a nutraceutical formulation containing Zingiber officinalis root extract and a standardized Thymus extract. It was administered as 1 ml/day twice a day for 90 days. Patients were assessed at baseline and after 1, 2 and 3 months of treatment, following a month of pharmacological washout by completing a questionnaire reporting the trend of the following symptoms: epigastric pain, epigastric heaviness, early satiety, belching, and regurgitation. Every symptom was assessed by a Visual Analogic Scale (VAS), ranging from 0= absence to 10= maximal severity. RESULTS We enrolled 272 patients (99 males and 173 females; median IQR age 49.5, 36-64 yrs). Obesity (BMI>30) was present in 28 (12.5%) patients; smokers were 83 (30.5%); and comorbidities were present in 107 (39.3%) patients. Improvement of symptom scores during treatment and one month after its suspension was extremely significant (p<0.000). CONCLUSION This large study found that nutraceutical formulation could be one of the tools for an empirical approach to treat patients with FD, especially when a non-conventional drug treatment is preferable for the patient and considered suitable by the physician.

Abstract
BACKGROUND Free and Cued Selective Reminding Test (FCSRT) is a reliable cognitive marker for Alzheimer's disease (AD), and the identification of neuropsychological tests sensitive to the early signs of AD pathology is crucial both in research and clinical practice. OBJECTIVE The study aimed to ascertain the ability of FCSRT in predicting the amyloid load as determined from amyloid PET imaging (Amy-PET) in patients with cognitive disorders. METHODS For our purpose, 79 patients (71 MCI, 8 mild dementia) underwent a complete workup for dementia, including the FCSRT assessment and a [18F]florbetaben PET scan. FCSRT subitem scores were used as predictors in different binomial regression models. RESULTS Immediate free recall and delayed free recall were the best predictors overall in the whole sample; whereas in patients <76 years, all models further improved with immediate total recall (ITR) and Index of Sensitivity of Cueing (ISC) resulting the most accurate in anticipating Amy-PET results, with a likelihood of being Amy-PET positive greater than 85% for ITR and ISC scores of less than 25 and 0.5, respectively. CONCLUSION FCSRT proved itself to be a valid tool in dementia diagnosis, also being able to correlate with amyloid pathology. The possibility to predict Amy-PET results through a simple and reliable neuropsychological test might be helpful for clinicians in the dementia field, adding value to a paper and pencil tool compared to most costly biomarkers.

Abstract
BACKGROUND The latest developments in Lewy Body Dementia (DLB) raise some controversies on clinical features, neuroimaging and therapy. The aim of our study is to determine clinical, neuropsychological, neuroimaging and EEG profile of DLB through retrospective and prospective data of 102 patients. METHODS data were collected with an analytical form that was developed by an expertise of neurologists. RESULTS DLB represented 4.8% of the dementia population, with no sex difference. Family history of dementia was common (24.5%), while familiarity for parkinsonism was rare (4.9%). Cognitive disturbances were the predominant clinical presentation at onset (49%), followed by behavioral symptoms (29.4%) and parkinsonism (21.6%). Clinical features at consultation were: memory disturbances (almost all cases), symmetrical (68.6%) or asymmetrical (18.6%) parkinsonism, cognitive fluctuations (49%), visuospatial deficits (53.9%), and visual hallucinations (44.1%). Autonomic signs were present in a third of the cases, while sleep disorders were present in 44.1%. Some clinical response to antiparkinsonian drugs was evident in half of the cases. MRI, SPET, EEG and Neuropsychiatric Inventory data were available in a subgroup of patients. CONCLUSIONS Most of our data were in accordance with the previous literature. However, some data underline the relationship between DLB, Alzheimer's and Parkinson's disease.

Abstract
BACKGROUND The aim of this study was to compare the effect of treatment with different cholinesterase inhibitors (ChEIs) on mental status and every day function in a natural outpatient clinic setting, so that this evaluation could more realistically reveal the effects which are likely to be observed in patients attending ordinary dementia clinics rather than in the context of a randomised controlled drug trial. METHODS Long term outcome of treatment with the ChEIs donepezil and rivastigmine was retrospectively evaluated in 147 patients with a clinical diagnosis of probable Alzheimer's disease of mild to moderate level of severity who had been monitored for a period of nine months. Measures included Mini Mental State Examination, Activity of Daily Living and Instrumental Activity of Daily Living scales. RESULTS Response rate was similar to that of other published clinical trials on ChEIs. Patients who responded well to treatment with ChEIs better maintained their improved performance. CONCLUSIONS Treatment with both ChEIs resulted in improved performance in those patients responding to therapy. Greater response was observed in previously untreated patients who had a shorter disease history but overall the findings in this unselected clinical sample confirmed that patients gain some benefit from intervention with ChEI treatment.

Abstract
Lyme disease is an infectious disease caused by the spirochete Borrelia burgdorferi. The course of the disease is divided into three stages, the second of which may include various types of peripheral nervous system disturbances. We report the case of a patient with persistent deficits caused by the prevalent involvement of the sciatic nerve, confirmed by electrophysiological and neuropathological findings. The most significant bioptic results were axonal degeneration and perivascular inflammation. Damage to a single peripheral nerve as the dominant clinical expression during the course of Lyme disease is an unusual finding that has been rarely described in the literature.

Abstract
Because of its pathophysiological and clinical peculiarities, true menstrual migraine (MM) (i.e. migraine starting exclusively between the days immediately before and immediately after the first day of the menstrual cycle) requires an ad hoc management different from that of other migraines. The paucity of well-conducted, controlled clinical trials and the lack of a universally accepted definition of MM have meant that the treatment of MM is still largely empirical. In our clinical practice, we adopt a sequential therapeutic approach, including the following steps: (i) acute attack drugs (sumatriptan, ergot derivatives, NSAIDs); (ii) intermittent prophylaxis with ergot derivatives or NSAIDs; (iii) oestrogen supplementation with percutaneous or transdermal oestradiol (100 microg patches); (iv) antioestrogen agents (danazol, tamoxifen).

Abstract
One of the most interesting glycosaminoglycans (GAGs) is heparansulphate, known as the physiological activator of antithrombin III and involved in the maintenance of the antithrombotic potential of uninjured endothelium. The aim of our study was to evaluate the tolerability and effectiveness of heparansulphate with respect to sulodexide, another GAG suitable for the treatment of venous diseases. The study was performed in a open-label, controlled, with parallel and randomized groups, design. Thirty patients (aged 32-72 years) suffering from superficial thrombophlebitis were treated for two weeks with heparansulphate 100 mg t.i.d. or sulodexide 250 LSU b.i.d., both given orally. Some coagulative and fibrinolytic parameters (PT; aPTT; fibrinogen; euglobulin lysis time; t-PA; PAI-1; ATIII; alpha 2-antiplasmin; D-Dimer and platelets count) were assayed at the beginning and at the end of the study. Moreover signs and symptoms of disease (skin trophism; local pain; itch and oedema) were assessed. Heparansulphate and sulodexide were able to reduce signs and symptoms with similar degree and to significantly modify t-PA, alpha 2-antiplasmin and ATIII levels without any difference between treatments. Our issues show that heparansulphate can be useful in superficial thrombophlebitis management.

Abstract
We evaluated the mesoglycan effects on the coagulative-fibrinolytic system in 10 patients with euglobulin lysis time (ELT) over 180 minutes. A mathematical model was used to analyze such phenomena. 100 mg of mesoglycan was administered to 10 patients for 14 days. The following parameters were evaluated: tissue plasminogen activator (t-PA), plasminogen activator inhibitor (PAI-1), euglobulin lysis time (ELT), plasminogen, alpha 2 antiplasmin, prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin clotting time (TCT), and fibrinogen. Those parameters were evaluated on the first and on the last day of the mesoglycan treatment at the following times: 0 (basal), 2, 4, 6, 8, 10 and 12 hours. Our results suggest that the mesoglycan is able to reduce a profibrinolytic activity without any influence on the coagulative-fibrinolytic system, at the baseline conditions and after chronic administration. The pharmacodynamic study and the statistical analysis using our mathematic model resulted to be statistically significant.

Abstract
In this study the profibrinolytic activity of two single oral doses of mesoglycan was evaluated. Furthermore, a mathematical model describing the patterns of the resulting phenomena was applied. Ten patients with impaired fibrinolytic system (euglobulin lysis time > 180 min) were enrolled in the study. In the morning following a 24 hour fast period, the patients were given orally a single dose (100 and 50 mg) of mesoglycan and placebo, with an interval of 48 hours between each treatment. The following parameters were evaluated at the time 0 and after 2, 4, 6, 8, 10 and 12 hours from each administration: tissue plasminogen activator (t-PA) and its inhibitor PAI-1, euglobulin lysis time, plasminogen and alfa-2-antiplasmin as indexes of the fibrinolytic system; aPTT, TT, fibrinogen as indexes of the hemostatic-coagulative system. Mesoglycan showed a dose-dependent profibrinolytic activity, that was also present after placebo but in a less entity. The mathematical study confirms the experimental observations and thus may allow to describe, with a high degree of approximation, the in vivo pharmacology of mesoglycan through the use of the mathematical function.

Abstract
The aim of this study was to evaluate the possible action in vitro of the platelets on the rheological behavior of red blood cells in healthy subjects and in patients with peripheral obliterative arterial disease before and after an isotonic exercise. Red blood cells and platelets from control subjects and from patients were tested in several ratios before and after the exercise studying the erythrocyte filterability. beta-thromboglobulin, a platelet-specific protein, was determined in vivo in all subjects before and after the exercise and in vitro as percent of increase between PPP and PRP activated, to monitor the platelet release. The results showed the interrelationship between platelet activation and rheological behavior of red blood cells.
