Parkinson's disease (PD) is the subject of intense efforts to develop strategies that slow down or stop disease progression and disability. Substantial evidence points to a prominent role for ...neuroinflammation in the underlying dopaminergic cell death. Ultramicronized palmitoylethanolamide (um-PEA) is well-known for its ability to promote the resolution of neuroinflammation and exert neuroprotection. This study was designed to assess the efficacy of um-PEA as adjuvant therapy in patients with advanced PD.
Thirty PD patients receiving levodopa were included in the study. The revised- Movement Disorder Society/Unified Parkinson's Disease Rating Scale (MDS-UPDRS) questionnaire was used to assess motor and non-motor symptoms. Clinical assessments were carried out before and after addition of um-PEA (600 mg). MDS-UPDRS questionnaire total score for parts I, II, III, and IV was analyzed using the Generalized Linear Mixed Model, followed by the Wilcoxon signed-rank test to evaluate the difference of each item's mean score between baseline and end of um-PEA treatment.
Addition of um-PEA to PD patients receiving levodopa therapy elicited a significant and progressive reduction in the total MDS-UPDRS score (parts I, II, III and IV). For each item, the mean score difference between baseline and end of um-PEA treatment showed a significant reduction in most nonmotor and motor symptoms. The number of patients with symptoms at basal was reduced after one year of um-PEA treatment. None of the participants reported side effects attributable to the addition of um-PEA.
um-PEA slowed down disease progression and disability in PD patients, suggesting that um-PEA may be an efficacious adjuvant therapy for PD.
Introduction
In patients with Parkinson’s disease (PD), impulsivity is still a matter of investigation. It has been hypothesized that impulsive personality traits may favour impulse control disorder ...(ICD) onset during dopaminergic therapy. In healthy subjects, a relationship between the awareness of motor intention and impulsive personality traits assessed by the Barratt impulsivity scale (BIS-11) has been reported. The aim of this study was to evaluate the relationship between the awareness of voluntary action and impulsivity traits in PD.
Methods
Twenty-eight PD patients (stages I-III on the Hoehn and Yahr scale) underwent an impulsivity trait assessment by the BIS-11 scale and a task based on the Libet’s clock. Participants were requested to perform a self-initiated movement and report the time they first feel their intention to move (W-judgement) or the time of the actual movement (M-judgement).
Results
In patients with higher BIS-11 scores, the time lag between the W-judgement and the actual movement was significantly lower than in patients with lower BIS-11. No difference emerged in the M-judgement.
Conclusion
Data suggest that also in PD patients, the impulsive personality trait is related to a “delayed” awareness of motor intention and therefore to a shorter interval to allow a conscious “veto” of the impending action. Characterization of the temporal profile of awareness of motor intention could prove useful in identifying PD patients at risk of developing ICDs during dopaminergic treatment.
Alcoholic drinks are a migraine trigger in about one third of patients with migraine in retrospective studies on trigger factors. Many population studies show that patients with migraine consume ...alcohol in a smaller percentage than the general population. Moreover, research has shown a decreased prevalence of headache with increasing number of alcohol units consumed. The classification criteria of alcohol-related headaches remain problematic. We discuss the role and mechanism of action of alcohol or other components of alcoholic drinks in relation to alcohol-induced headache. In accordance with data from a recent prospective study, we believe that reports overestimate the role of alcohol, as well as other foods, in the triggering of migraine. If a relationship between the intake of alcohol and the migraine attack is not clear, a small dose of alcohol is not contraindicated either for enjoyment or its protective effect on cardiovascular disease.
Subclinical paroxysmal atrial fibrillation (AF) is one of the main occult causative mechanisms of embolic stroke of undetermined source (ESUS). Aim of this study was to identify AF predictors, and to ...develop a score to predict the probability of AF detection in ESUS.
We retrospectively analyzed ESUS patients undergoing 2-week external electrocardiographic monitoring. Patients with and without AF detection were compared. On the basis of multivariate analysis, predictors of AF were identified and used to develop a predictive score, which was then compared with other existing literature scores.
Eighty-two patients, 48 females, mean age±SD 72±10 years, were included. In 36 patients (43.9%) AF was detected. The frequency of age 75 years or above and arterial hypertension, and the median CHA 2 DS 2 -VASc score were significantly higher in patients with AF compared with those without. National Institutes of Health Stroke Scale (NIHSS) score ≥8 was the only independent variable associated with AF detection. We derived the Empoli ESUS-AF (E 2 AF) score (NIHSS ≥8 5 points, arterial hypertension 3 points, age 75 years or above 2 points, age 65 to 74 years 1 point, history of coronary/peripheral artery disease 1 point, left atrial enlargement 1 point, posterior lesion 1 point, cortical or cortical-subcortical lesion 1 point), whose predictive power in detecting AF was good (area under the curve: 0.746, 95% confidence interval: 0.638-0.836) and higher than that of CHA 2 DS 2 -VASc and other scores.
In our study NIHSS score ≥8 was the only independent predictor of post-ESUS-AF detection. The E 2 AF score appears to have a good predictive power for detecting AF. External validations are required.
The safety profile of fingolimod is well established in clinical trials and post-marketing studies. This study aimed to evaluate the safety and tolerability of fingolimod in a cohort of Italian ...patients with relapsing-remitting multiple sclerosis (RRMS). This is a non-comparative, open-label, multicentre, interventional study conducted in patients with RRMS with no suitable alternative treatment option. Safety and tolerability of fingolimod 0.5 mg were assessed by recording adverse events (AEs) and serious AEs (SAEs). Of the 906 patients enrolled in the study, 91 % of the patients completed the study. AEs and SAEs were reported in 35.4 and 2.9 % of the patients, respectively. Most common AEs reported were headache (4.1 %), influenza (2.1 %), lymphopenia (1.8 %), asthenia (1.8 %) and pyrexia (1.8 %). Increased alanine aminotransferase levels and hypertension were reported as AE in 1.0 and 1.4 % of the patients, respectively. Macular oedema was reported in three patients. These results emphasize the safety of fingolimod in patients representing the real-world clinical practice in the Italian population. Fingolimod was safe and well tolerated in this population, which, compared to those enrolled in pivotal trials in terms of concomitant diseases and used medications, is broader.

Background:
The influence of pregnancy on long-term disability in multiple sclerosis (MS) is still controversial.
Objective:
To assess the risk of long-term disability worsening after pregnancy in MS ...women as compared with a propensity-score (PS) matched group of MS women without pregnancy.
Methods:
In the setting of the Italian Pregnancy Dataset, MS patients with (pregnancy group (PG)) and without pregnancy (control group (CG)) were recruited. Time to disability worsening on the Expanded Disability Status Scale (EDSS) was assessed through a multivariable Cox regression model.
Results:
The PS-matching retained 230 PG and 102 CG patients. After a follow-up of 6.5 +/- 3.1 years, disability worsening occurred in 87 (26.2%) women. In the multivariable analysis, disability worsening was associated with pregnancy in women with relapses in the year before conception (adjusted hazard ratio (aHR) = 1.74; 95% confidence interval (CI) 1.06–2.84; p = 0.027), higher EDSS (aHR = 1.39; 95% CI 1.12–1.74; p = 0.003), younger age (aHR = 0.95; 95% CI 0.91–0.99; p = 0.022) and shorter DMD exposure over the follow-up (p < 0.008).
Conclusion:
Pregnancy in MS women with relapses in the year before conception increases the risk of long-term disability worsening. Our findings underscore the importance of counselling in MS women facing a pregnancy that should be planned after a period of clinical stability, favouring treatment optimization in patients with recent disease activity.
Background:
The accrual of brain focal pathology is considered a good substrate of disability in relapsing–remitting multiple sclerosis (RRMS). However, knowledge on long-term lesion evolution and ...its relationship with disability progression is poor.
Objective:
The objective of this paper is to evaluate in RRMS the long-term clinical relevance of brain lesion evolution.
Methods:
In 58 RRMS patients we acquired, using the same scanner and protocol, brain magnetic resonance imaging (MRI) at baseline and 10±0.5 years later. MRI data were correlated with disability changes as measured by the Expanded Disability Status Scale (EDSS).
Results:
The annualized 10-year lesion volume (LV) growth was +0.25±0.5 cm3 (+6.7±8.7%) for T2-weighted (T2-W) lesions and +0.20±0.31 cm3 (+11.5±12.3%) for T1-weighted (T1-W) lesions. The univariate analysis showed moderate correlations between baseline MRI measures and EDSS at 10 years (p < 0.001). Also, 10-year EDSS worsening correlated with LV growth and the number of new/enlarging lesions measured over the same period (p < 0.005). In the stepwise multiple regression analysis, EDSS worsening over 10 years was best correlated with the combination of baseline T1-W lesion count and increasing T1-W LV (R = 0.61, p < 0.001).
Conclusion:
In RRMS patients, long-term brain lesion accrual is associated with worsening in clinical disability. This is particularly true for hypointense, destructive lesions.
Few data exists on predictive factors of hemorrhagic transformation (HT) in real-world acute ischemic stroke patients. The aims of this study were: (i) to identify predictive variables of HT (ii) to ...develop a score for predicting HT.
We retrospectively analyzed the clinical, radiographic, and laboratory data of patients with acute ischemic stroke consecutively admitted to our Stroke Unit along two years. Patients with HT were compared with those without HT. A multivariate logistic regression analysis was performed to identify independent predictors of HT on CT scan at 24 hours to develop a practical score.
The study population consisted of 564 patients with mean age 77.5±11.8 years. Fifty-two patients (9.2%) showed HT on brain CT at 24 hours (4.9% symptomatic). NIHSS score ≥8 at Stroke Unit admission (3 points), cardioembolic etiology (2 points), acute revascularization by systemic thrombolysis and/or mechanical thrombectomy (1 point), history of previous TIA/stroke (1 point), and major vessel occlusion (1 point) were found independent risk factors of HT and were included in the score (Hemorrhagic Transformation Empoli score (HTE)). The predictive power of HTE score was good with an AUC of 0.785 (95% CI: 0.749-0.818). Compared with 5 HT predictive scores proposed in the literature (THRIVE, SPAN-100, MSS, GRASPS, SITS-SIC), the HTE score significantly better predicted HT.
NIHSS score ≥8 at Stroke Unit admission, cardioembolism, urgent revascularization, previous TIA/stroke, and major vessel occlusion were independent predictors of HT. The HTE score has a good predictive power for HT. Prospective studies are warranted.
