The Effect of Blood Pressure on Rates of Progression in Focal Ischemic versus Generalized Cup Enlargement Glaucoma Phenotypes.

Purpose: To investigate the impact of blood pressure (BP) on rates of retinal nerve fiber layer (RNFL) thinning in glaucomatous eyes with focal ischemic (FI) versus generalized enlargement (GE) optic disc phenotypes.

Design: Prospective cohort study.

Participants: The study included 122 eyes from 101 patients diagnosed with primary open-angle glaucoma.

Vocal Instabilities in Untrained Female Singers.

Objectives: This study aimed to identify voice instabilities across registration shifts produced by untrained female singers and describe them relative to changes in fundamental frequency, airflow, intensity, inferred adduction, and acoustic spectra.

Study Design: Multisignal descriptive study.

Methods: Five untrained female singers sang up to 30 repetitions of octave scales.

Cognitive factors underlying mathematical skills: A systematic review and meta-analysis.

In understanding the nature of mathematical skills, the most influential theories suggest that mathematical cognition draws on different systems: numerical, linguistic, spatial, and general cognitive skills. Studies show that skills in these areas are highly predictive of outcomes in mathematics. Nonetheless, the strength of these relations with mathematical achievement varies, and little is known about the moderators or relative importance of each predictor.

Chemical profile, antioxidant, antifungal, and cytotoxic activities of propolis from the stingless bee Tetragona clavipes.

Propolis is derived from plant resin and bees' salivary secretions, are commonly used in folk medicine. Studies on propolis from stingless bees have increased in recent years, highlighting their relevance due to the variety of species and the bioactive components. However, scientific records confirming these activities in species occurring in Brazil are still scarce.

Resistance training for fatigue in people with cancer.

Background: Cancer-related fatigue (CRF) is one of the most common symptoms associated with cancer and its treatment. Different types of exercise have demonstrated beneficial effects on CRF. Previous evidence syntheses provided promising but inconclusive results when focusing on the effects of resistance training.
