The Impact of Socioeconomic Status on Visual Acuity Changes in Schoolchildren: A One-Year Follow-Up.

(1) Background: Visual acuity (VA) is essential for children's quality of life, and its relationship with socioeconomic status (SES) highlights disparities in healthcare. This study investigated the influence of SES on changes in schoolchildren's VA over one year. (2) Methods: Initial examinations were conducted on 1822 children (8-10 years).

Relationship between socioeconomic status and myopia in school children: CISViT project.

Purpose: Evidence indicates the existence of an association between socioeconomic status (SES) and the prevalence of myopia in the adult population. In contrast, there are limited studies investigating this association in children. The purpose of this study was to investigate the association between the presence of myopia in 8-year-old children from southern Europe and SES defined as parental educational level and employment status.

Agronomic performance and remote sensing assessment of organic and mineral fertilization in rice fields.

Introduction: Rice heavily relies on nitrogen fertilizers, posing environmental, resource, and geopolitical challenges. This study explores sustainable alternatives like animal manure and remote sensing for resource-efficient rice cultivation. It aims to assess the long-term impact of organic fertilization and remote sensing monitoring on agronomic traits, yield, and nutrition.

A new slit lamp-based technique for anterior chamber angle estimation.

Purpose: To design and test a new noninvasive method for anterior chamber angle (ACA) estimation based on the slit lamp that is accessible to all eye-care professionals.

Methods: A new technique (slit lamp anterior chamber estimation [SLACE]) that aims to overcome some of the limitations of the van Herick procedure was designed. The technique, which only requires a slit lamp, was applied to estimate the ACA of 50 participants (100 eyes) using two different slit lamp models, and results were compared with gonioscopy as the clinical standard.

Sources of variability of the van Herick technique for anterior angle estimation.

Background: The purpose of the present study was to investigate two potential sources of variability of the traditional van Herick technique for temporal anterior chamber angle estimation, namely the need to compare the depth of the peripheral anterior chamber (PACD) with the thickness of the peripheral cornea (PCT), and the possible loss of information resulting from restricting the assessment of the anterior chamber angle (ACA) to the temporal limbus.

Methods: Both image analysis and Scheimpflug photography were employed to measure PCT and PACD in a group of 82 eyes (mean ± SD age of 32.8 ± 4.

[Laparoscopic treatment of acute gastric volvulus].

Introduction: Gastric volvulus is an uncommon clinical condition and is associated with type ii-iii hiatal hernias. Its acute presentation constitutes a surgical emergency. Despite its low frequency, results of laparoscopic treatment have already been published.

Potential chemical and microbiological risks on human health from urban wastewater reuse in agriculture. Case study of wastewater effluents in Spain.

Potential health risks derived from wastewater reuse in agriculture have been evaluated with Risk Assessment modelling techniques, in a case study involving the effluents of two Spanish wastewater treatment plants. One of the plants applies primary and secondary treatment, and the other one applies an additional tertiary treatment. Health risks were assessed on the basis of ingesting contaminated food, due to exposure to: (i) 22 chemical pollutants, namely pharmaceuticals and personal care products (PPCPs), and priority pollutants included in the European Framework Directive, and (ii) microorganisms, namely enterovirus.

Design of an interferometric system for the measurement of phasing errors in segmented mirrors.

One of the new problems that has to be solved for segmented mirrors is related to periodic phasing, because for such mirrors to exhibit diffraction-limited performance the segments have to be positioned with an accuracy of a fraction of a wavelength. We describe the optical design of an instrument that measures the phasing errors (i.e.
