Effect of caffeine on vestibular evoked myogenic potential: a systematic review with meta-analysis.

Introduction: Caffeine can be considered the most consumed drug by adults worldwide, and can be found in several foods, such as chocolate, coffee, tea, soda and others. Overall, caffeine in moderate doses, results in increased physical and intellectual productivity, increases the capacity of concentration and reduces the time of reaction to sensory stimuli. On the other hand, high doses can cause noticeable signs of mental confusion and error induction in intellectual tasks, anxiety, restlessness, muscle tremors, tachycardia, labyrinthine changes, and tinnitus.

Effect of antioxidant supplementation on the auditory threshold in sensorineural hearing loss: a meta-analysis.

Introduction: Hearing loss is conceptualized as any impairment of the ability to hear and/or detect speech or environment sounds, regardless of cause, type, or degree. It may occur at different stages of life; during pregnancy or childbirth, in childhood, adulthood or old age. It should be noted that aging is the most common cause of sensorineural hearing loss followed by noise-induced hearing loss, and both are closely related to the formation of reactive oxygen species.

[Prevalence and factors associated with food and nutrition insecurity in families in municipalities of the north of the State of Alagoas, Brazil, 2010].

The scope of this study was to identify the prevalence and factors associated with food insecurity (INSEC) in families of northern Alagoas. A cross-sectional study was conducted with a random sample of 1444 households classified in accordance with the Brazilian INSEC scale into the following categories: mild, moderate or severe. The prevalence ratio calculated by Poisson regression was used to investigate the association of moderate + severe INSEC with the independent variables in both crude and adjusted analysis.

Can carbohydrate mouth rinse improve performance during exercise? A systematic review.

The purpose of this review was to identify studies that have investigated the effect of carbohydrate (CHO) mouth rinse on exercise performance, and to quantify the overall mean difference of this type of manipulation across the studies. The main mechanisms involving the potential benefit of CHO mouth rinse on performance was also explored. A systematic review was conducted in the following electronic databases: PubMed, SciELO, Science Direct, MEDLINE, and the Cochrane Library (Cochrane Central Register of Controlled Trials), without limit of searches.
