Vision-related quality of life and near-work visual symptoms in patients with attention-deficit/hyperactivity disorder.

Clinical Relevance: Attention-deficit/hyperactivity disorder (ADHD) has been associated with visual symptoms that may impact daily activities such as near-work tasks and social interactions. Addressing these visual issues is important for improving the overall quality of life and functional outcomes in individuals with ADHD, particularly in academic and social settings.

Purpose: To investigate the relationship between vision-related quality of life and near-work visual symptoms in patients with ADHD patients.

Melanoma-on-a-chip model for anticancer drug injecting delivery method.

The pharmaceutical and cosmetic industries are encountering a challenge in adopting new study models for product development. there has been a growing interest in organ-on-a-chip systems, and particularly for generating skin models. While numerous alternatives replicating high-fidelity skin models exist, there is a notable absence of melanoma study's methodology specifically on these microfluidic chips.

Differential response to preoperative exercise training in patients candidates to cardiac valve replacement.

Background: There is lack of evidence regarding safety, effectiveness and applicability of prehabilitation on cardiac surgery population, particularly in patients candidates to cardiac valve replacement. The aim of the study is to assess and compare the effect of a multimodal prehabilitation program on functional capacity in patients with severe aortic stenosis (AoS) and severe mitral regurgitation (MR) proposed for valve replacement surgery.

Methods: Secondary analysis from a randomised controlled trial whose main objective was to analyze the efficacy of a 4-6 weeks multimodal prehabilitation program in cardiac surgery on reducing postoperative complications.

General-purpose programmable photonic processor for advanced radiofrequency applications.

A general-purpose photonic processor can be built integrating a silicon photonic programmable core in a technology stack comprising an electronic monitoring and controlling layer and a software layer for resource control and programming. This processor can leverage the unique properties of photonics in terms of ultra-high bandwidth, high-speed operation, and low power consumption while operating in a complementary and synergistic way with electronic processors. These features are key in applications such as next-generation 5/6 G wireless systems where reconfigurable filtering, frequency conversion, arbitrary waveform generation, and beamforming are currently provided by microwave photonic subsystems that cannot be scaled down.
