Cortical Network Topological Modifications Underlie Clinical Evolution in the Acute Phase of Ischemic Stroke.

BackgroundFollowing stroke, brain networks can be described by strength of local connections (clustering coefficient [w]) and strength of global interconnections (path length [w]) between nodes, and their balance (Small-worldness [w]). . To identify electroencephalography (EEG) networks predicting clinical evolution in stroke through a multicenter cross-sectional study.

An early feasibility study for neurological devices: The ARCTRAN study.

Introduction: An Early Feasibility Study (EFS) is an exploratory clinical investigation of a device to optimize its design through iterative feedback loops during early clinical experience. The ARCTRAN study is an EFS aimed at analyzing efficacy, safety and adherence to the home-rehabilitation device-based (ARC Intellicare) program compared to a paper-based exercise protocol in patients with Parkinson's disease (PD), Multiple Sclerosis (MS) and stroke.

Materials And Methods: At baseline (T0), patients of each group were randomly divided into two arms, with a 1:1 ratio: an 'interventional' group received ARC Intellicare and a 'control' group received a paper-based rehabilitation protocol, both consisting of three 60-minute sessions/week for 8 weeks.

Treatment for ulnar neuropathy at the elbow.

Background: Ulnar neuropathy at the elbow (UNE) is the second most common entrapment neuropathy after carpal tunnel syndrome. Treatment may be conservative or surgical, but optimal management remains controversial. This is an update of a review first published in 2011 and previously updated in 2012 and 2016.

Association of Klotho and FGF23 with cardiovascular outcomes in diabetic older adults with chronic limb-threatening ischemia: a prospective study.

Peripheral arterial disease (PAD) is more prevalent in individuals with type 2 diabetes mellitus (T2DM). The most severe complication of PAD is chronic limb-threatening ischemia (CLTI), which is associated with major adverse cardiovascular events (MACE) and major adverse limb events (MALE) following lower limb revascularization (LER). This study investigates the relationship between baseline levels of Klotho and FGF23 and the risk of cardiovascular and limb-related outcomes after LER in a selected cohort of older adults.

Artificial intelligence to predict individualized outcome of acute ischemic stroke patients: The SIBILLA project.

Introduction: Formulating reliable prognosis for ischemic stroke patients remains a challenging task. We aimed to develop an artificial intelligence model able to formulate in the first 24 h after stroke an individualized prognosis in terms of NIHSS.

Patients And Methods: Seven hundred ninety four acute ischemic stroke patients were divided into a training (597) and testing (197) cohort.

Movement disorders following mechanical thrombectomy resulting in ischemic lesions of the basal ganglia: An emerging clinical entity.

Background And Purpose: Post-stroke movement disorders (PMDs) following ischemic lesions of the basal ganglia (BG) are a known entity, but data regarding their incidence are lacking. Ischemic strokes secondary to proximal middle cerebral artery (MCA) occlusion treated with thrombectomy represent a model of selective damage to the BG. The aim of this study was to assess the prevalence and features of movement disorders after selective BG ischemia in patients with successfully reperfused acute ischemic stroke (AIS).

The Immediate Effects of Immersive Virtual Reality on Autonomic Nervous System Function in Patients with Disorders of Consciousness after Severe Acquired Brain Injury: A Pilot Study.

Disorders of Consciousness (DoCs) after severe acquired brain injury involve substantial impairment of cognition and physical functioning, requiring comprehensive rehabilitation and support. Technological interventions, such as immersive Virtual Reality (VR), have shown promising results in promoting neural activity and enhancing cognitive and motor recovery. VR can induce physical sensations that may activate the Autonomic Nervous System (ANS) and induce ANS-regulated responses.

Timing of Antithrombotic Secondary Prevention in Patients with Intracranial Hemorrhage after Stroke Thrombolysis and Thrombectomy.

In patients with acute ischemic stroke, hemorrhagic transformation (HT) of infarcted tissue frequently occurs after reperfusion treatment. We aimed to assess whether HT and its severity influences the start of secondary prevention therapy and increases the risk of stroke recurrence. In this retrospective dual-center study, we recruited ischemic stroke patients treated with thrombolysis, thrombectomy or both.

Imbalance of Essential Metals in Traumatic Brain Injury and Its Possible Link with Disorders of Consciousness.

Dysfunction of the complex cerebral networks underlying wakefulness and awareness is responsible for Disorders of Consciousness (DoC). Traumatic Brain Injury (TBI) is a common cause of DoC, and it is responsible for a multi-dimensional pathological cascade that affects the proper functioning of the brainstem and brain consciousness pathways. Iron (Fe), Zinc (Zn), and Copper (Cu) have a role in the neurophysiology of both the ascending reticular activating system, a multi-neurotransmitter network located in the brainstem that is crucial for consciousness, and several brain regions.

Actigraphic Sensors Describe Stroke Severity in the Acute Phase: Implementing Multi-Parametric Monitoring in Stroke Unit.

Actigraphy is a tool used to describe limb motor activity. Some actigraphic parameters, namely Motor Activity (MA) and Asymmetry Index (AR), correlate with stroke severity. However, a long-lasting actigraphic monitoring was never performed previously.

Prognostic Role of Hemispherical Functional Connectivity in Stroke: A Study via Graph Theory Versus Coherence of Electroencephalography Rhythms.

Background: The objective of the present study is to explore whether acute stroke may result in changes in brain network architecture by electroencephalography functional coupling analysis and graph theory.

Methods: Ninety acute stroke patients and 110 healthy subjects were enrolled in different clinical centers in Rome, Italy, starting from 2013, and for each one electroencephalographies were recorded within <15 days from stroke onset. All patients were clinically evaluated through National Institutes of Health Stroke Scale, Barthel Index, and Action Research Arm Test in the acute stage and during the follow-up.

Dual anti-platelet therapy for secondary prevention in intracranial atherosclerotic disease: a network meta-analysis.

Background: Intracranial arterial stenosis (ICAS) is a non-marginal cause of stroke/transient ischemic attacks (TIAs) and is associated with high stroke recurrence rate. Some studies have investigated the best secondary prevention ranging from antithrombotic therapy to endovascular treatment (ET). However, no direct comparison between all the possible treatments is currently available especially between single and dual anti-platelet therapies (SAPT and DAPT).

Extensive corpus callosum ischemia after coronary artery bypass grafting on extracorporeal circulation.

Introduction: Heart surgery can be associated with adverse ischemic brain events.

Case Report: Here, we describe two patients who presented extensive infarction of the corpus callosum and of other brain watershed areas following coronary artery bypass grafting (CABG) on extracorporeal circulation (ECC).

Discussion: Infarction of the corpus callosum is an extremely rare condition due to its abundant blood supply.

Identification of Gait Unbalance and Fallers Among Subjects with Cerebellar Ataxia by a Set of Trunk Acceleration-Derived Indices of Gait.

This study aimed to assess the ability of 25 gait indices to characterize gait instability and recurrent fallers among persons with primary degenerative cerebellar ataxia (pwCA), regardless of gait speed, and investigate their correlation with clinical and kinematic variables. Trunk acceleration patterns were acquired during the gait of 34 pwCA, and 34 age- and speed-matched healthy subjects (HS) using an inertial measurement unit. We calculated harmonic ratios (HR), percent recurrence, percent determinism, step length coefficient of variation, short-time largest Lyapunov exponent (sLLE), normalized jerk score, log-dimensionless jerk (LDLJ-A), root mean square (RMS), and root mean square ratio of accelerations (RMSR) in each spatial direction for each participant.

Reach&grasp requires highly coordinated activation of different brain areas. We investigated whether reach&grasp kinematics is associated to EEG-based networks changes. We enrolled 10 healthy subjects.

Actigraphic Measurement of the Upper Limbs for the Prediction of Ischemic Stroke Prognosis: An Observational Study.

Background: It is often challenging to formulate a reliable prognosis for patients with acute ischemic stroke. The most accepted prognostic factors may not be sufficient to predict the recovery process. In this view, describing the evolution of motor deficits over time via sensors might be useful for strengthening the prognostic model.

Neuropathic Pain in the Elderly.

Neuropathic pain due to a lesion or a disease of the somatosensory system often affects older people presenting several comorbidities. Moreover, elderly patients are often poly-medicated, hospitalized and treated in a nursing home with a growing risk of drug interaction and recurrent hospitalization. Neuropathic pain in the elderly has to be managed by a multidimensional approach that involves several medical, social and psychological professionals in order to improve the quality of life of the patients and, where present, their relatives.
