Exploring Cardiac Sympathetic Denervation in Transthyretin-Mediated Hereditary Amyloidosis (ATTRv): Insights from I-mIBG Scintigraphy.

Hereditary transthyretin-mediated amyloidosis (ATTRv) is a rare disease characterized by the deposition of amyloid in the heart and peripheral nerves, particularly affecting small fibers. This study aims to evaluate autonomic cardiac involvement in ATTRv. Twelve patients with ATTRv and twelve sex- and age-matched healthy subjects underwent I-mIBG scintigraphy to evaluate the early and late heart-to-mediastinum ratio (eH/M and lH/M), Tc-HDP bone scan scintigraphy, and neurophysiological assessments.

Oxidative Stress in Transthyretin-Mediated Amyloidosis: An Exploratory Study.

Transthyretin-mediated amyloidosis (ATTR) is a systemic disease with protein precipitation in many tissues, mainly the peripheral nerve and heart. Both genetic (ATTRv, "v" for variant) and wild-type (ATTRwt) forms are known. Beyond the steric encumbrance, precipitated transthyretin seems to have a toxic effect.

Emotion recognition in amyotrophic lateral sclerosis in a dynamic environment.

Objective: The aim of our study was to measure the ability of ALS patients to process dynamic facial expressions as compared to a control group of healthy subjects and to correlate this ability in ALS patients with neuropsychological, clinical and neurological measures of the disease.

Methods: Sixty-three ALS patients and 47 healthy controls were recruited. All the ALS patients also underwent i) the Geneva Emotion Recognition Test (GERT) in which ten actors express 14 types of dynamic emotions in brief video clips with audio, ii) the Edimburgh Cognitive and Behavioral ALS Screen (ECAS) test; iii) the ALS Functional Rating Scale Revised (ALSFRS-R) and iv) the Medical Research Council (MRC) for the evaluation of muscle strength.

Chronic inflammatory demyelinating polyneuropathy and HEV antibody status: A case-control study from Lazio, Italy.

Introduction: Few studies have pointed to the possible role of infectious diseases in triggering Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). Given the association of Hepatitis E Virus (HEV) with Guillain Barrè syndrome, we conducted a case-control study to determine the possible association of HEV infection with CIDP, analyzing possible risk factors for acquiring HEV infection in both CIDP patients and controls.

Materials And Methods: 82 CIDP and 260 from the general population have provided some personal information (demographics, anamnestic data and recognized risk factors for HEV infection) and underwent venipuncture blood sampling for virological assays testing for anti-HEV IgG and IgM with ELISA and RNA-HEV performing RT-PCR.

Genetics screening in an Italian cohort of patients with Amyotrophic Lateral Sclerosis: the importance of early testing and its implication.

Introduction: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease with an elusive etiology. While environmental factors have been considered, familial ALS cases have raised the possibility of genetic involvement. This genetic connection is increasingly evident, even in patients with sporadic ALS.

Yttrium-90 Radioembolization of Colorectal Cancer Liver Metastases: A Systematic Review of Clinical Evidence.

The present work aims to review the clinical evidence of survival outcome after treatment of colorectal cancer liver metastases using yttrium-90 radioembolization, existence, and relevance of clinical, imaging, and genomic predictors of treatment efficacy and the amount of administered activity. Publications listed in PubMed between July 2016 and May 2021 were screened. Predictors of overall survival were reported and distinguished in clinical, imaging, and genomic variables.
