Asymmetries in foveal vision.

Visual perception is characterized by known asymmetries in the visual field; human's visual sensitivity is higher along the horizontal than the vertical meridian, and along the lower than the upper vertical meridian. These asymmetries decrease with decreasing eccentricity from the periphery to the center of gaze, suggesting that they may be absent in the 1-deg foveola, the retinal region used to explore scenes at high-resolution. Using high-precision eyetracking and gaze-contingent display, allowing for accurate control over the stimulated foveolar location despite the continuous eye motion at fixation, we investigated fine visual discrimination at different isoeccentric locations across the foveola and parafovea.

Efficacy of Lurasidone in First-Episode Psychosis: Patient Phenotypes, Dosage, and Recommendations from an Expert Panel.

Introduction: For patients with psychosis, early, intensive therapeutic intervention is thought to improve long-term outcomes. Furthermore, patients with a first-episode psychosis (FEP) who experience a good early response to antipsychotic medication show a clinical and functional benefit over the longer term if they continue low-dose antipsychotic treatment. Lurasidone is an atypical antipsychotic agent which is approved in Europe for the treatment of schizophrenia in adults and adolescents (13-17 years).

[Translation and validation of the Clinical Frailty Scale (CFS) into Spanish in Chile].

Introduction: The assessment of frailty is crucial for the management and care of older adults. The Clinical Frailty Scale (CFS) has been proposed as a useful and practical tool for this assessment, but its implementation requires translation and validation to the specific cultural context.

Methods: A standardized process of translation and cultural adaptation of the CFS in its second version was carried out.
