Impact of a School-Based Intervention on Sugar-Sweetened Beverage Intake Substitution by Water in Mexican Scholars.

Introduction: The prevalence of overweight and obesity in children has increased in recent years, associated with substituting plain water intake with sugar-sweetened beverages. The aim of the study was to evaluate the impact of a school-based intervention that aimed to replace sugar-sweetened beverages with water on Mexican scholars.

Methods: We included 314 children aged 9-11 from three public schools of the State of Hidalgo, Mexico, randomized to intervention (two schools from the municipality of Apan; six classes with 146 participants) or control group (one school from the municipality of Emiliano Zapata; six classes with 168 participants) and followed for 6 months.

Latency and amplitude changes in cognitive event related potentials due to hemodialysis.

Chronic kidney disease impacts the cognitive abilities of patients, and yet few works have analyzed functional electroencephalographic changes on event-related potentials before and after an hemodialysis session. This work shows that, as a consequence of hemodialysis, cognitive potential waveforms suffer changes, occurring with reduced latency $( \sim 50$ ms) and with larger amplitude $( \sim 0.128\mathrm {a}$.

Response to treatment during medium-term follow-up in a series of patients with neurocardiogenic syncope.

Background: Syncope is a common symptom that has different recurrence ratios. We hypothesized that an individualized treatment regimen including pharmacologic and nonpharmacologic measures considering kind of neurocardiogenic syncope (NCS) and basal characteristics of each patient could allow optimized therapy to avoid recurrences.

Methods: We conducted a prospective study to evaluate performance of diverse accepted treatments for NCS.
