Background and Purpose: In order to provide efficient and effective stroke care, The American Stroke Association recommends establishing stroke systems of care. Standardizing stroke care from a regional approach ensures patients receive consistent, evidence-based care. Many community and critical access hospitals lack resources needed for rapid transfer to the regional comprehensive stroke center (CSC) after treatment of an acute ischemic stroke. Single-bolus administration of IV tenecteplase (TNK) in community and critical access hospitals allows for immediate transfer of patients without the necessity of an hour-long infusion. There is supporting evidence for the use of TNK as an alternate for alteplase (ALT) for the treatment of suspect ischemic stroke. The purpose of this poster is to demonstrate the effectiveness of a regional initiative in the transition to the use of TNK over ALT to improve door-in-door-out (DIDO) times. Methods: CSC leadership held meetings and educational sessions with key stakeholders from referring hospitals across the region to discuss the feasibility and advantages of transitioning to TNK for stroke treatment. A TNK toolkit was provided which included dosing and safety information, sample order sets, cost-effectiveness, and consent information. DIDO times of hospitals using TNK were compared to those hospitals using alteplase over an 8-month period. Results: There were 37 patients included in the analysis, with 21 receiving ALT and 16 receiving TNK over the study period. Median DIDO times for ALT patients were 195.5 minutes while median DIDO times for TNK patients were 178.5 minutes. There were no major complications noted. Conclusions: DIDO times for TNK-treated patients appear to be less than those treated with ALT. As more regional hospitals begin to use TNK for suspected stroke, continued monitoring of DIDO times will be required. Additional analysis of DIDO data from transferring hospitals transitioned to TNK is needed. Regional change in stroke systems of care impacting multiple hospitals across a wide geographic area is feasible and impacts the efficiency of treatment. Additional study is needed to determine if the effect is sustainable and results in improved outcomes.

Introduction: Movement Disorder Society (MDS) new diagnostic criteria for Progressive Supranuclear palsy (PSP) identifying different disease phenotypes were recently released. The aim of the present study is to report on the cognitive and behavioral features of the different phenotypes diagnosed according to the MDS criteria. Methods: Forty-nine PSP patients underwent an extensive battery of clinical assessments. Differences between PSP subtypes were computed with χ2 or ANOVA tests. Using the z scores, subjects were classified as having normal cognition, mild cognitive impairment, single or multiple domain, and dementia. A logistic regression model was implemented to investigate the major determinants of PSP non-Richardson’s syndrome phenotype. Results: Half of the cohort presented Richardson’s syndrome (46.9%), followed by PSP with parkinsonism and corticobasal syndrome (22.4% and 14.2%, respectively). Richardson’s syndrome and PSP with corticobasal syndrome presented a similar burden of disease. The only cognitive testing differentiating the phenotypes weresemantic fluency and ideomotor apraxia. The majority of our cohort was either affected by dementia or presented normal cognition. Richardson’s syndrome presented the highest rate of dementia. The only marker of PSP non-Richardson’s syndrome phenotype was better performance in visuo-spatial testing, implying worse visuo-spatial abilities in PSP Richardson’s syndrome. Conclusion: Available clinical assessments hardly capture differences between PSP phenotypes. The cognitive testing differentiating the PSP phenotypes were semantic fluency and ideomotor apraxia. In PSP, mild cognitive impairment likely represents an intermediate step from normal cognition to dementia. The only marker of PSP non-Richardson’s syndrome phenotype was better performance in visuo-spatial testing.

Post-prandial hyperglycemia can be relevant in developing early manifestations of atherosclerosis. EVOO (Extra Virgin Olive Oil), rich in saturated fatty acids and commonly used in the Mediterranean diet, seems to control post-prandial hyperglycemia better than butter. Subjects with type 1 diabetes are at higher risk of developing cardiovascular disease and show endothelial dysfunction, an early manifestation of atherosclerosis in the first years of the disease. Our study aims to evaluate whether EVOO and butter influence endothelial function in subjects with type 1 diabetes when added to a single high glycemic index (HGI) meal. In this exploratory cross-over study, 10 subjects with type 1 diabetes and 6 healthy subjects were scheduled to receive two types of HGI meals: one enriched with EVOO and one with butter. Before and after each test meal at different time points, all subjects underwent the evaluation of endothelial function by flow-mediated dilation technique, glucose and lipids measurements, and gastric emptying assessment by ultrasound. Flow-mediated dilation significantly increased after EVOO-enriched meal compared with butter in subjects with type 1 diabetes (two-way-repeated measurements ANOVA, p = 0.007). In patients with type 1 diabetes, the add-on of EVOO to HGI meal improves vascular function compared to butter, which has detrimental effects.

Diet, visceral sensitivity, and psychological distress play an important role in Irritable Bowel Syndrome (IBS). This study focused on the relation between IBS severity, foods, visceral sensitivity, and anxiety/depression.Patients with IBS were investigated through (1) IBS-symptoms severity score (SSS), (2) self-reported food intolerance, (3) visceral sensitivity index (VSI), and (4) Hospital Anxiety and Depression Scale (HADS). Seventy-seven patients agreed to participate in the survey. Of them, 64 (83%) showed IBS according to Rome IV criteria and were included in the final analysis. Patients with IBS-D were 30 (47%), with IBS-C 27 (42%), and with IBS-M 7 (11%).Fifty-eight patients (90%) considered at least one foodstuff as IBS trigger. Amine-rich foods represented a symptom trigger for 77% of patients, those with lectin for 70%, IACs by 48%, and capsaicin by 37%. Overweight was significantly associated with amine-rich foods (p=0.015), age45 years (p=0.001) and non-smoking condition (p=0.033) with lectin-rich foods, male gender (p=0.005) and overweight (p=0.027) with capsaicin-containing foods. A positive VSI score was found in 59% of patients, and non-smoking condition was significantly associated (OR 10.03; p=0.009). No factors were associated with a positive HADS score, shown by 80% of patients. Severe IBS was shown by 63% of patients, being amine-rich foods (p=0.024), overweight (p=0.020), and female gender (p=0.029) independent risk factors while marriage/cohabiting a protective one (p=0.038). Amine-rich foods are an independent risk factor for severe IBS, along with overweight and female gender.Clinicians should pay more attention to self-reported food intolerance in IBS patients. A personalized therapy including dietary advice as part of treatment could be of great benefit.

BACKGROUND Variants in GBA are the most common genetic risk factor for Parkinson's disease (PD). The impact of different variants on the PD clinical spectrum is still unclear. OBJECTIVES We determined the frequency of GBA-related PD in Italy and correlated GBA variants with motor and nonmotor features and their occurrence over time. METHODS Sanger sequencing of the whole GBA gene was performed. Variants were classified as mild, severe, complex, and risk. β-glucocerebrosidase activity was measured. The Kaplan-Meier method and Cox proportional hazard regression models were performed. RESULTS Among 874 patients with PD, 36 variants were detected in 14.3%, including 20.4% early onset. Patients with GBA-PD had earlier and more frequent occurrence of several nonmotor symptoms. Patients with severe and complex GBA-PD had the highest burden of symptoms and a higher risk of hallucinations and cognitive impairment. Complex GBA-PD had the lowest β-glucocerebrosidase activity. CONCLUSIONS GBA-PD is highly prevalent in Italy. Different types of mutations underlie distinct phenotypic profiles. © 2020 International Parkinson and Movement Disorder Society.

Objective To perform the genetic characterization of a cohort with familial parkinsonism and cognitive-behavioral syndrome. Methods A Next Generation Sequencing – based targeted sequencing of 32 genes associated to various neurodegenerative phenotypes, plus a screening for SNCA Copy Number Variations and C9orf72 repeat expansion, was applied in a cohort of 85 Italian patients presenting with parkinsonism and cognitive and/or behavioral syndrome and a positive familial history for any neurodegenerative disorder (i.e., dementia, movement disorders, amyotrophic lateral sclerosis). Results Through this combined genetic approach, we detected potentially relevant genetic variants in 25.8% of patients with familial parkinsonism and cognitive and/or behavioral syndrome. Peculiar phenotypes are described (Cortico-basal syndrome with APP, Posterior Cortical Atrophy with GBA, Progressive Supranuclear Palsy-like with GRN, Multiple System Atrophy with TARDBP). The majority of patients presented a rigid-bradykinetic parkinsonian syndrome, while rest tremor was less common. Myoclonic jerks, pyramidal signs, dystonic postures and vertical gaze disturbances were more frequently associated with the presence of a pathogenic variant in one of the tested genes. Conclusions Given the syndromic approach adopted in our study, we were able to provide a detailed clinical description of patients beyond the boundaries of specific clinical diagnoses and describe peculiar phenotypes. This observation further supports the knowledge that genetic disorders present phenotypic overlaps across different neurodegenerative syndromes, highlighting the limitations of current clinical diagnostic criteria defining sharp boundaries between distinct conditions.

Multiple chemical sensitivity (MCS) is characterised by non-specific and recurring symptoms affecting multiple organs and associated with exposure to chemicals, even at low concentrations, which are, under normal circumstances, harmless to the general population. Symptoms include general discomfort, cardiovascular instability, irritation of the sensory organs, breath disorders, hypersensitivity affecting the skin and epithelial lining of the gut, throat and lungs, anxiety, and learning and memory loss. Chemical intolerance is a key distinguishing feature of MCS, limiting considerably patients’ lifestyle with serious social, occupational and economic implications. Since no specific diagnostic markers are currently available for chemical intolerance, the diagnosis relies on clinical symptoms. Despite the formulation of several hypotheses regarding the pathophysiology of MCS, its mechanisms remain undefined. A person-centred care approach, based on multidisciplinary and individualised medical plans, has shown promising results. However, more definite treatment strategies are required. We have reviewed the main experimental studies on MCS pathophysiology, focusing on the brain networks involved, the impact of environmental pollution on the olfactory system and the correlation with other pathologies such as neurodegenerative diseases. Finally, we discuss treatment strategies targeting the olfactory system.

Key Clinical Message This study shows that neuromuscular taping improves gait, balance, pain and ability to walk and conduct daily activities in a multiple sclerosis patient. It is the first study to identify a panel of miRNAs modulated throughout rehabilitation using neuromuscular taping in a multiple sclerosis patient.

Multiple System Atrophy is a severe neurodegenerative disorder which is characterized by a variable clinical presentation and a broad neuropathological spectrum. The pathogenic mechanisms are almost completely unknown. In the present study, we established a cellular model of MSA by using fibroblasts' primary cultures and performed several experiments to investigate the causative mechanisms of the disease, with a particular focus on mitochondrial functioning. Fibroblasts' analyses (7 MSA-P, 7 MSA-C and 6 healthy controls) displayed several anomalies in patients: an impairment of respiratory chain activity, in particular for succinate Coenzyme Q reductase (p

Cancer is one of the most common causes of death worldwide. Available treatments are associated with numerous side effects and only a low percentage of patients achieve complete remission. Therefore, there is a strong need for new therapeutic strategies. In this regard, pulsed electromagnetic field (PEMF) therapy presents several potential advantages including non‐invasiveness, safety, lack of toxicity for non‐cancerous cells, and the possibility of being combined with other available therapies. Indeed, PEMF stimulation has already been used in the context of various cancer types including skin, breast, prostate, hepatocellular, lung, ovarian, pancreatic, bladder, thyroid, and colon cancer in vitro and in vivo. At present, only limited application of PEMF in cancer has been documented in humans. In this article, we review the experimental and clinical evidence of PEMF therapy discussing future perspectives in its use in oncology.
