Impact of Disease-Modifying Therapies on Gut-Brain Axis in Multiple Sclerosis.

Multiple sclerosis is a chronic, autoimmune-mediated, demyelinating disease whose pathogenesis remains to be defined. In past years, in consideration of a constantly growing number of patients diagnosed with multiple sclerosis, the impacts of different environmental factors in the pathogenesis of the disease have been largely studied. Alterations in gut microbiome composition and intestinal barrier permeability have been suggested to play an essential role in the regulation of autoimmunity.

Comparative Study of the Efficacy of Anti-CGRP mAbs on Migraineurs: Analysis of the First Year of Therapy, 1-Month Suspension Period, and Reprisal.

Few studies compare the clinical effectiveness of the three anti-CGRP mAbs. Moreover, no studies compare their efficacy during suspension and reprisal. Our study aimed to compare the efficacy of migraine frequency, intensity, and symptomatic medication intake during the first year of therapy, a 1-month suspension period, and a 3-month drug reprisal.

Ischemic strokes in COVID-19: risk factors, obesity paradox, and distinction between trigger and causal association.

Background And Purpose: Stroke has been described as a COVID-19 complication. However, its occurrence rate, risk factors, and causal relationships are still not well established.

Methods: We describe the characteristics of confirmed COVID-19-related strokes among all cases of COVID-19 hospitalized in our health network, from November 1, 2020 to April 30, 2021.

The use of alteplase, although safe, does not offer clear clinical advantages when mild stroke is non-disabling.

Introduction: It is unknown whether alteplase is effective and safe in patients with mild acute ischemic stroke (AIS). Determining whether symptoms are "disabling" or not is a crucial factor in the management of these patients. This study aimed to investigate the efficacy and safety of alteplase in patients with mild, non-disabling AIS.

Meningioma-Related Epilepsy: A Happy Ending?

(1) Background: More than one-third of patients with meningiomas experience at least one seizure during the course of their disease, and in the 20-50% of cases, seizure represents the onset symptom. After surgery, up to 30% of patients continue to have seizures, while others may experience them later; (2) Methods: The study analyzed retrospectively the risk factors for pre-operative seizures in a large cohort of 358 patients who underwent surgery for newly diagnosed brain meningioma; (3) Results: We identified age, peritumor edema, and location as risk factors for seizure at the onset. Patients with seizures differed from patients without seizures for the following characteristics: younger average age, lower pre-operative Karnofsky Performance Status (KPS), location on the convexity, lower Simpson Grade, lower incidence of pre-operative neurological deficits, and higher incidence of pre-operative peritumor edema.

2:1 ketogenic diet and low-glycemic-index diet for the treatment of chronic and episodic migraine: a single-center real-life retrospective study.

Aims: The evidence supporting the efficacy of dietary preventive therapy in migraine is rising, particularly regarding the ketogenic diet. However, less evidence exists for the Low-Glycemic Index Diet and the 2:1 KD. This retrospective single-center real-life study aims to evaluate the efficacy of a 2:1 ketogenic diet and a Low-Glycemic-index Diet in chronic and high-frequency episodic migraine.

Stress hyperglycemia as a modifiable predictor of futile recanalization in patients undergoing mechanical thrombectomy for acute ischemic stroke.

Introduction: Mechanical thrombectomy (MT) is the first line treatment in acute ischemic stroke (AIS) due to large vessel occlusion (LVO). Approximately half of patients treated with MT does not have a favorable outcome 3 months after stroke. The aim of this study was to identify predictors of futile recanalization (FR) in patients with LVO treated with MT.

Sleep of migraine patients is ameliorated by ketogenic diet, independently of pain control.

Objective/background: Migraine patients are frequently affected by sleep complaints. The ketogenic diet (KD) is an option for the treatment of migraine. Our aim was: 1) to assess the effects of KD on sleep complaints in patients affected by migraine and 2) to verify if sleep changes were related to the effects of the diet on headache symptoms.

Efficacy and safety of two different botulinum toxin type A dilutions in chronic migraineurs.

Botulinum toxin type A is an effective preventive therapy for chronic migraine. Although the guidelines suggest a 50U/ml dilution of OnabotulinumtoxinA (BoNT/A), many clinicians use more concentrated solutions. However, there are no studies regarding the effect and safety of 100U/ml BoNT/A dilution with the saline solution following the PREEMPT paradigm.

Effect of Dexmedetomidine versus Propofol on Intraoperative Seizure Onset During Awake Craniotomy: A Retrospective Study.

Objective: The effect of dexmedetomidine (DEX) compared with propofol on intraoperative seizures (IOSs) detected using electrocorticography during awake craniotomy for resection of brain tumors is unknown. This investigation aimed to compare IOS rate in patients receiving DEX versus propofol as sedative agent.

Methods: In this retrospective single-center study, awake craniotomies performed from January 2014 to December 2019 were analyzed.

Hyperdense middle cerebral artery sign predicts favorable outcome in patients undergoing mechanical thrombectomy.

Non-contrast computer tomography detects the presence of hyperdense middle cerebral artery sign (HMCAS). Studies on the prognostic value of HMCAS among patients undergoing mechanical thrombectomy (MT) are conflicting. A retrospective analysis of consecutive patients with acute ischemic stroke due to middle cerebral artery occlusion, presenting with or without HMCAS, who underwent MT, was performed.

Disease Activity and Progression in Multiple Sclerosis: New Evidences and Future Perspectives.

Multiple sclerosis (MS) is a chronic, debilitating, autoimmune-mediated, inflammatory disease of the central nervous system (CNS), in which a combination of inflammation, demyelination and axonal degeneration takes place with extreme highly interpersonal variability [...

Performing real time neuropsychological testing during awake craniotomy: are dexmedetomidine or propofol the same? A preliminary report.

Purpose: In awake surgery, the patient is sedated, but is also required to be sufficiently alert and collaborative during extensive neurocognitive testing. In the present preliminary report of a retrospective single-center study, a continuous series of 168 patients who underwent awake surgery for brain tumor located near eloquent areas, was investigated to observe the effect of dexmedetomidine (n = 58) compared with propofol (n = 110) on vigilance and collaboration required to perform extensive intra-operatory Real Time Neuropsychological Testing (RTNT).

Methods: We assigned a score to each patient, by using a scale that combines vigilance and collaboration in a 5 levels score (the higher score denoting higher level).

New-onset Myasthenia Gravis after SARS-CoV-2 infection: case report and literature review.

We report the case of a 19-year-old female patient who developed Myasthenia Gravis 13 days after SARS-CoV-2 infection with positive RT-PCR testing. Her symptoms initially involved the oculo-bulbar district, but they gradually worsened in 3 months converting into a generalized form of Myasthenia Gravis complicated with a myasthenic crisis. A high level of anti-acetylcholine receptor antibodies was found in the serum, while anti-MuSK antibodies were negative; Repetitive Nerve Stimulation and Single-fiber Electromyography were suggestive of Myasthenia Gravis.

Stress Hyperglycemia Does Not Affect Clinical Outcome of Diabetic Patients Receiving Intravenous Thrombolysis for Acute Ischemic Stroke.

Although stress hyperglycemia represents a main risk factor for poor outcome among patients with acute ischemic stroke (AIS) undergoing recanalization therapy, we have limited information regarding a possible influence of the premorbid diabetic status on this association. We recruited consecutive patients admitted to the Udine University Hospital with AIS who were treated with intravenous thrombolysis (IVT) from January 2015 to September 2020. On the basis of the premorbid diabetic status, our sample was composed of 130 patients with and 371 patients without diabetes.

Neurological disorders in COVID-19: a case of Acute Disseminated Encephalomyelitis in an adult patient.

Different neurological complications associated with the severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection have been widely documented. Acute disseminated encephalomyelitis (ADEM) is a rare immune-mediated demyelinating disorder, described within the spectrum of neurological manifestations of COVID-19. Herein, we describe a case of adult-ADEM presenting with diplopia and slowly progressive ataxia developed one month after SARS-CoV-2 infection.

Erenumab Impact on Sleep Assessed With Questionnaires and Home-Polysomnography in Patients With Migraine: The ERESON Study.

Introduction: Migraine and sleep share a complex and unclear relationship. Poor sleep may trigger migraine attacks; migraine, in turn, is frequently associated with sleep disorders. Few previous studies used questionnaires to assess sleep changes in patients who were treated with migraine-preventive medications (MPMs).

Stress Hyperglycemia in Patients With Acute Ischemic Stroke Due to Large Vessel Occlusion Undergoing Mechanical Thrombectomy.

Stress hyperglycemia may impair outcomes in patients with acute ischemic stroke (AIS) undergoing mechanical thrombectomy (MT). The glucose-to-glycated hemoglobin ratio (GAR) was used to measure stress hyperglycemia. Data from our database of consecutive patients admitted to the Udine University Hospital with AIS who were treated with MT between January 2015 and December 2020 were retrospectively analyzed.

Recanalisation theraphy for acute ischemic stroke in cancer patients.

To date, very few studies focused their attention on efficacy and safety of recanalisation therapy in acute ischemic stroke (AIS) patients with cancer, reporting conflicting results. We retrospectively analysed data from our database of consecutive patients admitted to the Udine University Hospital with AIS that were treated with recanalisation therapy, i.e.

Stress hyperglycemia is predictive of worse outcome in patients with acute ischemic stroke undergoing intravenous thrombolysis.

No study investigated the possible detrimental effect of stress hyperglycemia on patients affected acute ischemic stroke (AIS) undergoing intravenous thrombolysis (IVT). A new index, the glucose-to-glycated hemoglobin ratio (GAR), has been developed for assessing stress hyperglycemia. We retrospectively analyzed data from a prospectively collected database of consecutive patients admitted to the Udine University Hospital with AIS that were treated with IVT from January 2015 to December 2019.

Dynamic Hyperglycemic Patterns Predict Adverse Outcomes in Patients with Acute Ischemic Stroke Undergoing Mechanical Thrombectomy.

Background: Admission hyperglycemia impairs outcome in acute ischemic stroke (AIS) patients undergoing mechanical thrombectomy (MT). Since hyperglycemia in AIS represents a dynamic condition, we tested whether the dynamic patterns of hyperglycemia, defined as blood glucose levels > 140 mg/dl, affect outcomes in these patients.

Methods: We retrospectively analyzed data of 200 consecutive patients with prospective follow-up.
