Serological and molecular epidemiology of the Dengue, Zika and Chikungunya viruses in a risk area in Brazil.

Background: The co-circulation of types of arbovirus in areas where they are endemic increased the risk of outbreaks and limited the diagnostic methods available. Here, we analyze the epidemiological profile of DENV, CHIKV and ZIKV at the serological and molecular level in patients with suspected infection with these arboviruses in the city of Juazeiro do Norte, Ceará, Brazil.

Methods: In 2016, the Central Public Health Laboratory (LACEN) of Juazeiro do Norte received 182 plasma samples from patients who visited health facilities with symptoms compatible with arbovirus infection.

LC-MS/MS profiles and interrelationships between the enzyme inhibition activity, total phenolic content and antioxidant potential of Micromeria nervosa extracts.

The objective of this study was to quantify the phenolic compounds and to evaluate and compare the biological activities of the ethyl acetate (EtOAc), methanolic (MeOH) and aqueous extracts from the Micromeria nervosa aerial parts, based on their antioxidant activity and enzymatic inhibition. Total phenolic and flavonoid contents were calculated and individual compo3unds were detected using LC-ESI-MS/MS. The antioxidant activity was determined using six different assays while enzymatic activity was determined by α-amylase and tyrosinase enzyme inhibition.

Low handgrip strength levels among adolescents in a city in southern Brazil.

Objective: To estimate the prevalence of low handgrip strength (HGS) levels and sociodemographic characteristics, health behaviours and body fatness status related in adolescents.

Method: Cross-sectional epidemiological study with 636 adolescents aged 14-19 years in a city in southern Brazil. HGS was measured by dynamometer.

[Anthropometric indicators of obesity in the prediction of high body fat in adolescents].

Objective:: To determine the anthropometric indicators of obesity in the prediction of high body fat in adolescents from a Brazilian State.

Methods:: The study included 1,197 adolescents (15-17 years old). The following anthropometric measurements were collected: body mass (weight and height), waist circumference and skinfolds (triceps and medial calf).
