Among 421 family members evaluated through cascade screening, 127 (30%), were diagnosed and medically treated. Nine family members from 25 (40%) patients who underwent implantable cardioverter defibrillator (ICD) implantation have experienced appropriate ICD shock.

A rigorous, systematic protocol in a specialized inherited arrhythmia clinic has a high diagnostic and prognostic yield. ECG, 12 lead Holter and family screening significantly increased the diagnostic yield. In nine families, without genetic testing, the diagnosis would have been missed.

Between August 2019 and October 2019, a total of 559 young male adults were subjected to an online survey sponsored by social networks with the aim of assessing their sexual habits. The following questionnaires were administered The International Index of Erectile Function (IIEF-5), Masturbation Erection index (MEI), Pornography Craving Questionnaire (PCQ) and Asexuality Identification Scale (AIS). The overall rate of ED according to IIEF-5 was 26.0% (165/478), the rate of ED according to MEI was 16.9% (81/478) and the rate ED in patients with AIS ≥23 indicating asexual trait was 10.0% (48/478). We found that IIEF-5 was positively associated with MEI (b = 0.32; p less then .01) and negatively with AIS (b = -0.36; p less then .01) and MEI was negatively associated with AIS (b = -0.36; p less then .01). We found that MEI (odds ratio [OR] 0.86; p less then .01) and IIEF-5 (OR 0.89; p less then .01) were inversely associated with asexual trait. The presence of asexual trait can hide a greater risk of finding ED both in intercourse or masturbation. These results should be taken into consideration during the general assessment of the patient with sexual problems.
Duchenne muscular dystrophy (DMD) is caused by mutations in the DMD gene resulting in the absence of dystrophin. Casimersen is a phosphorodiamidate morpholino oligomer designed to bypass frameshift DMD mutations and produce internally truncated, yet functional, dystrophin protein in patients amenable to exon 45 skipping. Our primary study objective was to evaluate safety and tolerability of casimersen; the secondary objective was to characterize the plasma pharmacokinetics.

This multicenter, phase 1/2 trial enrolled 12 participants (aged 7-21 years, who had limited ambulation or were nonambulatory) and comprised a 12-week, double-blind dose titration, then an open-label extension for up to 132 weeks. During dose titration, participants were randomized 21 to weekly casimersen infusions at escalating doses of 4, 10, 20, and 30 mg/kg (≥2 weeks per dose), or placebo.

Participants received casimersen for a mean 139.6 weeks. Treatment-emergent adverse events (TEAEs) occurred in all casimersen- and placebo-treated participants and were mostly mild (over 91.4%) and unrelated to casimersen or its dose. There were no deaths, dose reductions, abnormalities in laboratory parameters or vital signs, or casimersen-related serious AEs. Casimersen plasma concentration increased with dose and declined similarly for all dose levels over 24 hours postinfusion. All pharmacokinetic parameters were similar at weeks 7 and 60.

Casimersen was well tolerated in participants with DMD amenable to exon 45 skipping. BMS-986235 molecular weight Most TEAEs were mild, nonserious, and unrelated to casimersen. Plasma exposure was dose proportional with no suggestion of plasma accumulation. These results support further studies of casimersen in this population.

X-linked adrenoleukodystrophy (X-ALD) is a rare genetic disorder characterized by progressive demyelination ranging from mild myelopathic forms (adrenomyeloneuropathy [AMN]) to severe cerebral variants (adult cerebral adrenoleukodystrophy [ACALD]). The aim of this study was to compare cognitive function in adult-onset X-ALD phenotypes.

Cognitive function in various domains (intelligence, attention, memory, executive function, and processing speed) was assessed in 172 adults (117 with AMN, 30 with arrested ACALD, and 25 with acute ACALD) using comprehensive neuropsychological batteries. Phenotype differences were examined by analyses of variance.

X-ALD phenotypes significantly differed in nonverbal intelligence, sustained attention, verbal encoding, nonverbal recognition, and processing speed (ps < 0.050). No group differences emerged regarding verbal intelligence, verbal retrieval and recognition, and executive function (ps > 0.050). Specifically, patients with acute ACALD showed severe cognitive auses white matter dementia, mainly characterized by an extreme slowdown in processing speed associated with deficits in attention and learning. Most patients with AMN show intact cognitive function. Future prospective, longitudinal studies with more sensitive imaging techniques are required to clarify whether early mild cognitive dysfunction found in some patients with AMN may be associated with subtle myelin abnormalities that do not yet appear as white matter lesions on cerebral MRI (cMRI) but have the potential to serve as early predictors of later cerebral progression. ANN NEUROL 2021;90266-273.Four pigeons were exposed to a tandem variable-interval (VI) fixed-ratio (FR) schedule in the presence of a 50-pixel (about 15 mm) square or an 80-pixel (about 24 mm) square and to a tandem VI differential-reinforcement-of-low-rate (DRL) schedule when a second 80-pixel or 50-pixel square was present. The values of the VI and FR schedules were adjusted to equate reinforcement rates in the two tandem schedules. Following this, a square-size continuum generalization test was administered under a fixed-interval (FI) schedule or extinction. In the first testing session, response frequency was a graded function of the similarity of the test stimuli to the training stimuli for all pigeons. These systematic generalization gradients persisted longer under the FI schedule than under extinction.
