A simple psychophysical procedure separates representational and noise components in impairments of speech prosody perception after right-hemisphere stroke.

After a right hemisphere stroke, more than half of the patients are impaired in their capacity to produce or comprehend speech prosody. Yet, and despite its social-cognitive consequences for patients, aprosodia following stroke has received scant attention. In this report, we introduce a novel, simple psychophysical procedure which, by combining systematic digital manipulations of speech stimuli and reverse-correlation analysis, allows estimating the internal sensory representations that subtend how individual patients perceive speech prosody, and the level of internal noise that govern behavioral variability in how patients apply these representations.

Neuromodulation of the Right Motor Cortex of the Lips With Repetitive Transcranial Magnetic Stimulation to Reduce Phonological Impairment and Improve Naming in Three Persons With Aphasia: A Single-Case Experimental Design.

Purpose: Repetitive transcranial magnetic stimulation (rTMS) can enhance aphasia recovery. Most studies have used inhibitory stimulation targeting the right inferior frontal gyrus. However, the motor cortex, observed to contribute to the prediction of aphasia recovery, is involved in word production and could be an appropriate target for rTMS.

Dementia and glaucoma: Results from a Nationwide French Study between 2006 and 2018.

Purpose: Glaucoma is the leading cause of irreversible blindness worldwide. The brain and eye share many characteristics, so the eye may provide an easy-access window on brain processes. The aim of the study was to evaluate the link between glaucoma as well as intraocular pressure (IOP)-lowering drops load and all-cause dementia.

Benefits of a targeted rehabilitation of number transcoding in secondary acalculia: A single-case experimental design.

Background: Despite its potentially significant functional and emotional impact, acalculia is still too rarely assessed and managed by speech and language therapists. Research on the rehabilitation of numerical transcoding remains scarce in the literature and, despite positive results, presents a low level of evidence.

Aims: The present study aims to evaluate the effectiveness of a targeted rehabilitation of numerical transcoding in two patients suffering from a chronic secondary acalculia.

Repeated awake surgery and quality of life in patients with diffuse glioma: a systematic review and meta-analysis.

Diffuse gliomas significantly affect patients' daily lives. Because of the high risk of recurrence and anaplasic transformation, repeated surgery can be proposed in awake condition to prolongs overall survival by limiting and reducing residual tumour volume. However, oncological interest alone is no longer sufficient due to the consequent increase in median survival, and quality of life is becoming an important issue in clinical decision-making.

Improving the stability of thiol-maleimide bioconjugates via the formation of a thiazine structure.

Linker stability is critically important for the efficacy and safety of peptide and protein conjugates used for biological applications. One common conjugation strategy, thiol-maleimide coupling, generates a succinimidyl thioether linker with limited stability under physiological conditions. We have shown in previous work that when a peptide with an N-terminal cysteine is conjugated to a maleimide reagent, a thiazine structure is formed via a chemical rearrangement.

Discordance between Anterior Segment Anatomy and Axial Length in Cataract Surgery Candidates in France.

Introduction: The aims of this study were to study ocular biometric data and their association with age and sex in a population of cataract surgery candidates and to assess the proportion of inhomogeneous eyes and the ratio anterior segment (AS) to axial length (AL). Multicentric cross-sectional analysis was conducted between April 2008 and May 2021 in public and private ophthalmic institutions in Montpellier, France. Individuals ≥40 years old who underwent ocular biometry before cataract surgery were included.

Retinal Microcirculation Changes in Crohn's Disease Patients under Biologics, a Potential Biomarker of Severity: A Pilot Study.

Crohn's disease (CD) is associated with increased cardiovascular risk and the retinal microcirculation is a reflection of the systemic microcirculation. Is the retinal microcirculation altered in relation to the severity of Crohn's disease? This cross-sectional case-controlled study was conducted in a university hospital center from November 2020 to February 2021. We prospectively included patients with moderate (biologic therapy) or severe (biologic therapy + peri-anal disease and/or digestive resection) CD and age- and sex-matched controls.

Assessment tools and rehabilitation treatments for aprosodia following acquired brain injury: A scoping review.

Background: Acquired brain injury (ABI), especially to the right hemisphere, can result in difficulty using or understanding prosodic contours in speech. Prosody is used to convey emotional connotation or linguistic intent and includes pitch, loudness, rate, and voice quality. A disorder in the comprehension or production of prosody is known as aprosodia; despite the communication disability caused by prosodic disorders, the assessment and treatment of aprosodia following ABI has received scant attention.

Cataract extraction and intraocular pressure-lowering agents delivery: A nationwide French study between 2005 and 2017.

Purpose: Cataract and glaucoma are among the leading causes of blindness worldwide in older people, and they are often concomitant. To assess topical intraocular (IOP)-lowering agents delivery changes after cataract extraction.

Material And Methods: Longitudinal matched exposed-unexposed study from the French national healthcare database from January 1, 2005 to January 1, 2017.

Depression and routinization following stroke.

Objective: Post-stroke depression is a frequent complication of stroke that has detrimental consequences for quality of life and functional outcomes. Daily life routines may increase feelings of security for some individuals confronted with age-related health concerns, but little information is available concerning their role following stroke. The aim of this investigation was to examine the association of depression and other psychological variables at hospitalization for stroke and behavioral routines and mood symptoms three months later using Ecological Momentary Assessment (EMA).

Efficacy, Safety, and Retreatment Benefit of Micropulse Transscleral Cyclophotocoagulation in Glaucoma.

Precis: Micropulse transscleral cyclophotocoagulation (MP-TSCPC) with a 120-second setting reduces intraocular pressure (IOP) with a 6-month success of 45.5%. Only late (>6 mo) failure seem to present a benefit for retreatment.

Sequence sensitivity and pH dependence of maleimide conjugated N-terminal cysteine peptides to thiazine rearrangement.

Thiazine formation during the conjugation of N-terminal cysteine peptides to maleimides is an underreported side reaction in the peptide literature. When the conjugation was performed at neutral and basic pH, we observed the thiazine isomer as a significant by-product. Nuclear magnetic resonance (NMR) spectroscopy confirmed the structure of the six-membered thiazine and ultra-high performance liquid chromatography (UHPLC) combined with tandem mass spectrometry (MS/MS) allowed for facile, unambiguous detection due to a unique thiazine mass fragment.
