Dysphonia Screening in Firefighters and Associated Factors.

Objective: To verify the likelihood of dysphonia in firefighters and its relationship with individual and occupational factors and mental health.

Method: This cross-sectional observational study with 442 firefighters collected data on sociodemographic, occupational, and lifestyle aspects and screening for common mental disorders (CMD). Individuals were divided into two groups: those slightly likely and those moderately/highly likely to have dysphonia, according to the Brazilian Dysphonia Screening Tool.

Skeletal muscle mass increases after viral eradication with direct-acting antivirals in patients with chronic hepatitis C: A longitudinal study.

Background: Results of studies evaluating the effect of viral eradication following direct-acting antiviral (DDA) therapy on skeletal muscle mass of patients with chronic hepatitis C (CHC) are scarce.

Aim: To assess the components of sarcopenia (low muscle mass, low muscle strength and low physical performance) in a cohort of CHC individuals before and after DAA therapy.

Methods: We performed a longitudinal study of patients with CHC who underwent body composition assessment before (T0), and at 12 (T1) and 48 (T2) weeks after DDA therapy.

Effects of different temperatures on testis structure and function, with emphasis on somatic cells, in sexually mature Nile tilapias (Oreochromis niloticus).

The Nile tilapia (Oreochromis niloticus) is economically one of the most important freshwater fish and is an excellent model for studies under laboratory conditions. Temperature is considered a very important modulator of reproductive activity in fish, although few studies have specifically addressed the effects of this key factor on morphological and functional aspects of teleost testes. Therefore, our main objectives in the present study were to analyze the effects of different temperatures (20, 25, 30, and 35 degrees C) on testicular somatic and germ cells in sexually mature Nile tilapias.
