Exploring reduction of prolonged binocular vision testing time: the agreement between the first and second thirty seconds within one minute of accommodative and vergence facility tests.

The study sought to compare the number of cycles (NOS) for the first and second thirty-seconds (FASTS) within 1 min of accommodative facility (AF) and vergence facility (VF) testing to explore possibilities of reducing testing time to 30 s. In this cross-sectional study, a multistage sample of school children (aged 8-17 years) was taken through ocular-visual screening. Eligible participants (586) underwent refraction, stereo-acuity measurement, AF testing using ± 2D lens flippers, and VF testing using 3 BI/12 BO flipper prisms.

Uptake and in-vitro bioaccessibility of toxic metals in cocoa beans: Human health risks.

Cocoa-growing areas in Ghana have experienced a rise in mining activities affecting cocoa cultivation and increased concentrations of potentially toxic metals in the soil, which can accumulate in cocoa beans. This study evaluated potential toxic metal contamination in cocoa beans and soils from cocoa farms in mining and non-mining areas in Ghana. We used X-ray fluorescence and an ICP-MS to determine metal concentrations, and a Zeeman mercury analyzer to determine mercury.

Smartphone Google Location History: A Novel Approach to Outdoor Physical Activity Research.

Background: Outdoor physical activity (PA) is an important component of overall health; however, it is difficult to measure. Passively collected smartphone location data like Google Location History (GLH) present an opportunity to address this issue.

Objectives: To evaluate the use of GLH data for measuring outdoor PA.
