Mutagenic damage among bronchiectasis patients attending in the pulmonology sector of a hospital in southern Brazil.

Objective: Bronchiectasis is a chronic respiratory disease characterized by inflammation, irreversible dilation of the bronchi, and recurrent pulmonary infections, with a high morbidity and mortality rate, but is less studied from the point of view of its prevalence and associated factors not directly related to respiratory prognosis. As it is a disease related to the exacerbation of the inflammatory process and oxidative stress, this study searched to investigate the micronucleus frequency in patients with and without bronchiectasis treated at a specialized pulmonology service in a hospital in the extreme south of Brazil.

Methods: Patients with a confirmed tomographic diagnosis of bronchiectasis were defined as cases.

and its Effects on the Prognosis of Bronchiectasis.

Bronchiectasis, which is an abnormal and irreversible dilation of one or several bronchial segments, causes significant morbidity and impaired quality of life to patients, mainly as the result of recurrent and chronic respiratory infections. is a microorganism known for its high infectious potential related to the production of molecules with great pathogenic power, such as enzymes, toxins, adhesins, and biofilm, which determine the degree of severity of systemic symptoms and can induce exacerbated immune response. This review highlighted the clinical significance of colonization/infection in bronchiectasis patients, since little is known about it, despite its increasing frequency of isolation and potential serious morbidity.

[Low back pain among adolescents in the semiarid region: results of a population census in the city of Caracol, State of Piauí, Brazil].

The scope of this article is to assess low back pain prevalence and associated factors in the last 12 months among adolescents in a city in the south of the State of Piauí. It was a cross-sectional study which included 1,112 adolescents aged 13-19 in the city of Caracol, Piauí. Demographic, socio-economic, nutritional, behavioral and comorbidty characteristics were investigated.
