Using the ATN system as a guide for the neuropsychological assessment of Alzheimer's disease.

Introduction: Many studies have attempted to determine whether Alzheimer's disease (AD) in-vivo biomarkers can predict neuropsychological performance since pathophysiological changes precede cognitive changes by several years. Nonetheless, neuropsychological measures can also detect cognitive deterioration in cognitively normal individuals with AD-positive biomarkers. Recent studies have investigated whether cognitive measures can be used as a proxy for biomarkers.

Lymphopenia during treatment with dimethyl fumarate in patients with multiple sclerosis: Prevalence, predicting factors and clinical outcomes.

Background: Lymphopenia is a common side effect of treatment with dimethyl fumarate (DMF) in patients with multiple sclerosis (PwMS). Prevalence and predictive factors of this side effect are still uncertain, because literature has provided discrepant results and it is still a matter of debate if lymphopenia is associated with a better treatment outcome.

Methods: We retrospectively recruited PwMS treated for at least one month with DMF and collected clinical, demographic data and absolute lymphocyte count (ALC) during follow-up.

Effects of the timing and intensity of treatment on septic shock patients treated with CytoSorb: Clinical experience.

Introduction: A group of adult septic shock patients treated with hemoperfusion (HA) with the Cytosorb associated with CVVHD were studied to determine (a) the effects of this technique on different clinical variables; and (b) the impact of the pre CytoSorb interval and its intensity on the outcome.

Methods: The catecholamine index (CI) and the pressure-catecholamine Index (PCAI) were used to assess the amount of catecholamine administered at baseline and during the procedure, respectively. The pre-treatment time was calculated since the onset of the septic-shock related hypotension and the initiation of the first session and the intensity was assessed considering either the total volume of blood processed and the duration of the HA.

Paraneoplastic neurological syndromes associated with non-Hodgkin lymphoma: a case series.

Background: Paraneoplastic neurological syndromes (PNS) associated with lymphoma are rare diseases that usually have different peculiar features when compared to PNS associated with solid neoplasms.

Methods: We retrospectively identified patients with NHL-associated PNS. Clinical and demographic data are reported.

National Institutes of Health stroke scale score at admission can predict functional outcomes in patients with ischemic stroke undergoing carotid endarterectomy.

Objective: The aim of present study was to evaluate the prognostic effect of the National Institutes of Health stroke scale (NIHSS) score for patients who had undergone acute carotid endarterectomy (CEA) and assess the clinical and morphologic factors that could predict for worse outcomes.

Methods: The data from 183 consecutive patients who had undergone CEA after ischemic stroke were analyzed from January 2015 to January 2021. The patients were divided into two groups using the NIHSS score cutoff of 4.

Dexamethasone and postoperative analgesia in minimally invasive thoracic surgery: a retrospective cohort study.

Background: Dexamethasone is commonly used for the prevention of postoperative nausea and vomiting (PONV), and recent reviews suggest a role for dexamethasone in postoperative analgesia. The aim of this study is to evaluate the efficacy of dexamethasone as an analgesic adjuvant in minimally invasive thoracic surgery. Primary outcome was morphine consumption 24 h after surgery; secondary outcomes were pain control, measured as numeric rating scale (NRS), glycemic changes, PONV, and surgical wound infection.

Trabecular bone porosity and pore size distribution in osteoporotic patients - A low field nuclear magnetic resonance and microcomputed tomography investigation.

The study of bone morphology is of great importance as bone morphology is influenced by factors such as age and underlying comorbidities and is associated with bone mechanical properties and fracture risk. Standard diagnostic techniques used in bone disease, such as Dual-Energy X-ray absorptiometry and ultrasonography do not provide qualitative and quantitative morphological information. In recent years, techniques such as High Resolution Computed Tomography (HR-CT), micro- CT, Magnetic Resonance Imaging (MRI), and Low Field Nuclear Magnetic Resonance (LF-NMR) have been developed for the study of bone structure and porosity.

Effects of autophagy inhibition by chloroquine on hepatic stellate cell activation in CCl4-induced acute liver injury mouse model.

Background And Aim: Hepatic stellate cells (HSCs) activation, a critical event in liver fibrosis, has been recently shown to be related to autophagy. Determine whether chloroquine (CQ) could affect (i) the activation of HSC in vivo and (ii) the hepatic damage in a mice acute liver injury model.

Methods: The acute liver injury was induced in BALB/c mice by carbon tetrachloride (CCl group); 24 h before and after CCl administration animals were treated by CQ (CCl  + CQ group).

Combined use of rheology and portable low-field NMR in cystic fibrosis patients.

Background: As most cystic fibrosis (CF) patients progress to respiratory failure, lung functionality assessment is pivotal. We previously developed a test that indirectly monitors airways (inflammation/functional test) by measuring the spin-spin relaxation time (T) of the water hydrogens present in CF sputum. Here the T significance in the monitoring of CF lung disease was further investigated by studying the correlation of T with: 1) sputum viscoelasticity, 2) mucociliary clearability index (MCI)/cough clearability index (CCI) and 3) sputum average mesh-size.

Xenograft Zebrafish Models for the Development of Novel Anti-Hepatocellular Carcinoma Molecules.

Hepatocellular carcinoma (HCC) is the sixth most common type of tumor and the second leading cause of tumor-related death worldwide. Liver cirrhosis is the most important predisposing factor for HCC. Available therapeutic approaches are not very effective, especially for advanced HCC, which is the most common form of the disease at diagnosis.

Leptospirosis is a zoonosis caused by infection with pathogenic strains of the bacterium Leptospira. The disease can be complicated by pulmonary hemorrhages and acute respiratory distress syndrome, with the mortality rate increasing to 51-100%. We report the case of a 37-year-old man who was admitted to the emergency department with a 6-day history of fever, weakness, vomiting and diarrhea, followed by jaundice.

Oscillatory EEG-TMS Reactivity in Parkinson Disease.

Purpose: A dysfunction of beta oscillatory activity is the neurophysiological hallmark of Parkinson disease (PD). How cortical activity reacts to external perturbations may provide insight into pathophysiological mechanisms. This study aims at identifying modifications in EEG rhythms after transcranial magnetic stimulation (TMS) in PD.

Surgeon-performed ultrasound for the staging of acute diverticulitis: Preliminary results of a prospective study.

Introduction: Although contrast-enhanced abdominal computed tomography (CEACT) is still considered the criterion standard for the assessment of suspected acute diverticulitis, in recent years, the use of point-of-care ultrasound (POCUS) has been spreading more and more in this setting. The aim of this study was to compare CEACT to POCUS for the diagnosis and staging of suspected acute diverticulitis.

Methods: This is a prospective study conducted on 55 patients admitted to the emergency department of two Italian Hospitals with a clinical suspicion of acute diverticulitis between January 2014 and December 2017.

Prognostic interaction between age and sex on outcomes following carotid endarterectomy.

The aim of this study was to assess the prognostic interaction between age and sex on peri-operative and follow-up outcomes following elective carotid endarterectomy (CEA) for asymptomatic and symptomatic carotid stenosis. A retrospective review of all patients admitted to a single vascular unit who underwent elective CEA between January, 2015 and December, 2019 was performed. The primary endpoints of the study were overall survival (from index operation) and cumulative stroke rate at thirty days.

Trend of emergency general surgery procedures during COVID-19 pandemic.

Background: In early 2020, the novel coronavirus infection (COVID-19) spread rapidly throughout the whole world, causing a massive response in terms of health resource disposal. Moreover, lockdowns were imposed in entire countries. This study aims to assess whether there was a downward trend in emergency general surgery (EGS) procedures accomplished throughout the COVID-19 pandemic and to determine patients' and diseases' characteristics.

Bortezomib in anti-N-Methyl-d-Aspartate-Receptor (NMDA-R) encephalitis: A systematic review.

N-methyl-d-aspartate receptor (NMDAR) encephalitis is a potentially treatable condition, although a small proportion of patients remains refractory to immunotherapy. Bortezomib is a proteasome inhibitor that has a promising role in autoimmune conditions. We performed an independent PubMed search employing "Anti-N-Methyl‑D-Aspartate encephalitis AND bortezomib", including papers published between January 1st, 2007 to April 15th, 2021.

Cerebrospinal fluid and serum interleukins 6 and 8 during the acute and recovery phase in COVID-19 neuropathy patients.

This case series describes three patients affected by severe acute respiratory syndrome coronavirus 2, who developed polyradiculoneuritis as a probable neurological complication of coronavirus disease 2019 (COVID-19). A diagnosis of Guillain Barré syndrome was made on the basis of clinical symptoms, cerebrospinal fluid analysis, and electroneurography. In all of them, the therapeutic approach included the administration of intravenous immunoglobulin (0.

Alpha-synuclein seeds in olfactory mucosa and cerebrospinal fluid of patients with dementia with Lewy bodies.

In patients with suspected dementia with Lewy bodies, the detection of the disease-associated α-synuclein in easily accessible tissues amenable to be collected using minimally invasive procedures remains a major diagnostic challenge. This approach has the potential to take advantage of modern molecular assays for the diagnosis of α-synucleinopathy and, in turn, to optimize the recruitment and selection of patients in clinical trials, using drugs directed at counteracting α-synuclein aggregation. In this study, we explored the diagnostic accuracy of α-synuclein real-time quaking-induced conversion assay by testing olfactory mucosa and CSF in patients with a clinical diagnosis of probable ( = 32) or prodromal ( = 5) dementia with Lewy bodies or mixed degenerative dementia (dementia with Lewy bodies/Alzheimer's disease) ( = 6).

ASL MRI and 18F-FDG-PET in autoimmune limbic encephalitis: clues from two paradigmatic cases.

Background: Autoimmune limbic encephalitis (LE) is a neurological condition characterized by seizures and cognitive dysfunction. Fluorine-18 fluorodeoxyglucose (18F-FDG-PET) has recently proved to be an important diagnostic tool in this condition since it may highlight brain metabolism abnormalities in a very early stage of the disease. Two main 18F-FDG-PET patterns have been described: the mixed hypermetabolic/hypometabolic and the neurodegenerative one.

Telemedicine during the SARS-Cov-2 pandemic lockdown: Monitoring stress and quality of sleep in patients with epilepsy.

SARS-CoV-2 pandemic heavily hit the western healthcare system saturating the hospital beds in wards and clogging the emergency departments. To avoid the collapse of Italian hospitals, office visits to outpatients were limited to emergencies and the general population went in a lockdown state. Physicians had to approach new problems in the management of chronic patients who could not leave their homes.

Nabiximols and botulinum toxin injections for patients with multiple sclerosis: efficacy on spasticity and spasms in a single-centre experience.

Background: Spasticity is a common and disabling symptom in patients with multiple sclerosis (PwMS): as highlighted by many epidemiological studies, it is often a severe and not well treated. Despite the availability of evidence-based spasticity management guidelines, there is still great variability in everyday therapeutic approach, especially for the most complex cases.

Methods: In our single-centre study, we retrospectively evaluated PwMS-treated nabiximols and botulinum toxin injections (BTI) from July 2015 to April 2019.
