Evaluating the contribution of the gene TARDBP in Italian patients with amyotrophic lateral sclerosis.

Background And Objectives: Genetic variants in the gene TARDBP, encoding TDP-43 protein, are associated with amyotrophic lateral sclerosis (ALS) in familial (fALS) and sporadic (sALS) cases. Objectives of this study were to assess the contribution of TARDBP in a large cohort of Italian ALS patients, to determine the TARDBP-associated clinical features and to look for genotype-phenotype correlation and penetrance of the mutations.

Methods: A total of 1992 Italian ALS patients (193 fALS and 1799 sALS) were enrolled in this study.

Analysis of CA repeats in italian ALS patients shows no association.

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease caused by a complex interaction of genetic and environmental factors. Recently, a polymorphic intronic CA repeat in gene has been proposed as risk factor for ALS. The presence of long/long CA genotype, especially if one allele had 24 CA, was reported to be significantly associated with the disease in a cohort of sporadic ALS patients.

Oral anticoagulants in fragile patients with percutaneous endoscopic gastrostomy and atrial fibrillation: the ORIGAMI pilot investigation.

Background: Extensive data support the superior safety without any trade-off in efficacy of direct oral anticoagulants (DOACs) compared to vitamin K antagonists (VKA) in patients with nonvalvular atrial fibrillation, deep venous thrombosis or pulmonary embolism. Whether DOACs may be successfully used to treat complex and fragile patients with percutaneous endoscopic gastrostomy (PEG) remains to be proven. The purpose of this pilot study was to evaluate the feasibility, anticoagulant effect, and preliminary safety/efficacy profile of edoxaban administered via PEG in patients with an indication for long-term oral anticoagulation.

Thr124Met myelin protein zero mutation mimicking motor neuron disease.

Mutations in myelin protein zero () are associated with heterogeneous manifestations. In this study, we report clinical, electrophysiological, pathological, and muscle MRI findings from two relatives with Thr124Met variants, disclosing different phenotypes. The proband was a 73-year-old female with a 12-year-story of atrophy, weakness, and fasciculations in her proximal and distal lower limbs.

Novel variants and cellular studies on patients' primary fibroblasts support a role for NEK1 missense variants in ALS pathogenesis.

In the last few years, NEK1 has been identified as a new gene related to amyotrophic lateral sclerosis (ALS). Loss-of-function variants have been mostly described, although several missense variants exist, which pathogenic relevance remains to be established. We attempted to determine the contribution of NEK1 gene in an Italian cohort of 531 sporadic and familial amyotrophic lateral sclerosis (ALS) patients applying massive parallel sequencing technologies.

Sustained safe and effective anticoagulation using Edoxaban via percutaneous endoscopic gastrostomy.

Extensive data support the safety of direct oral anticoagulants compared with vitamin K antagonists in patients with non-valvular atrial fibrillation, leading to a significantly increase in the use of these compounds in clinical practice. However, there is no compelling evidence supporting the use of direct oral anticoagulant in individuals who are intubated or have a percutaneous endoscopic gastrostomy (PEG): patients with several co-morbidities are underrepresented in clinical trials, so the best long-term strategy for anticoagulation is difficult to ascertain. The aim of the present report was to evaluate the safety and efficacy of edoxaban administered via PEG in a patient with heart failure and a history of atrial fibrillation affected by amyotrophic lateral sclerosis (ALS).

Prevalence and predictor factors of respiratory impairment in a large cohort of patients with Myotonic Dystrophy type 1 (DM1): A retrospective, cross sectional study.

Introduction: Respiratory complications are relevant in DM1, leading to a significantly increased morbidity and mortality risk in these patients; however, so far only few studies concerning respiratory function have been conducted in DM1 patients. We report a retrospective, multicenter, cross sectional study on a large cohort of DM1 patients widely characterized in the phenotype, to assess prevalence and identify predictors of restrictive respiratory syndrome.

Methods: 268 DM1 subjects aged >18 years, who had recently performed spirometric tests were included; restrictive syndrome was diagnosed if forced vital capacity (FVC) <80% of predicted.

ATXN1 intermediate-length polyglutamine expansions are associated with amyotrophic lateral sclerosis.

To clarify the possible involvement of intermediate ATXN1 alleles as risk factors for amyotrophic lateral sclerosis (ALS), we tested ATXN1 in a cohort of 1146 Italian ALS patients, previously screened for variants in other ALS genes, and in 529 controls. We detected ATXN1 alleles with ≥33 polyglutamine repeats in 105 of 1146 patients (9.16%) and 29 of 529 controls (5.

Matrin 3 variants are frequent in Italian ALS patients.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by loss of motor neurons in the primary motor cortex, brainstem, and spinal cord. Recently, missense variants in MATR3 were identified in familial and sporadic ALS patients, but very few additional ALS patients have been reported so far. The p.

Contribution of major amyotrophic lateral sclerosis genes to the etiology of sporadic disease.

Objectives: To quantify the overall contribution of mutations in the currently known amyotrophic lateral sclerosis (ALS) genes in a large cohort of sporadic patients and to make genotype-phenotype correlations.

Methods: Screening for SOD1, TARDBP, FUS, ANG, ATXN2, OPTN, and C9ORF72 was carried out in 480 consecutive patients with sporadic ALS (SALS) and in 48 familial ALS (FALS) index patients admitted to a single Italian referral center.

Results: Mutations were detected in 53 patients, with a cumulative frequency of 11.

Uncovering amyotrophic lateral sclerosis phenotypes: clinical features and long-term follow-up of upper motor neuron-dominant ALS.

The aim of our study was to analyse the natural history and clinical features of upper motor neuron- dominant (UMN-D) ALS. We studied a large series of sporadic ALS patients admitted in a single referral centre over a 23-year period. UMN-D phenotype was compared with other ALS forms, including classic ALS, flail arm and progressive muscular atrophy.
