Profile of fluency in spontaneous speech, reading, and retelling of texts by adults who stutter.

Purpose: to describe the profile of fluency concerning the typology of disfluencies, speed, and frequency of disruptions in spontaneous speech, reading, and retelling; to compare the fluency profile in adults who stutter in spontaneous speech, reading, and retelling of text.

Methods: The present work is a cross-sectional comparative study with a sample composed of 15 adults who stutter of both sexes, with higher education or equivalent to complete elementary school II. Samples were collected in the tasks of spontaneous speech, reading, and text retelling through video calls made individually with the participants.

Contextual and local determinants associated with the achievement of goals in the endodontics specialty in Brazilian dental speciality centres: A multilevel analysis.

Objectives: To assess which factors were associated with the achievement of endodontic goals.

Methods: Cross-sectional study using secondary data from the second cycle of the Program for the Improvement of Access and Quality in the dental speciality centres-in Portuguese PMAQ-CEO. The independent variables extracted from this database were related to dental speciality centres (CEO in Portuguese).

Effects of lidocaine and esmolol on hemodynamic response to tracheal intubation: a randomized clinical trial.

Introduction And Objectives: Although lidocaine is widely used to prevent cardiovascular changes resulting from laryngoscopy and orotracheal intubation, it is still unclear whether there are more efficacious drugs. This study aimed to compare the beta-blocker esmolol with lidocaine regarding the effects on hemodynamic response after orotracheal intubation.

Methods: The study has a prospective, randomized, double-blind, superiority design, and assessed 69 participants between 18 and 70 years of age, ASA I-II, scheduled for elective or emergency surgery under general anesthesia with orotracheal intubation.

Nucleophilic Fluorination with KF Catalyzed by 18-Crown-6 and Bulky Diols: A Theoretical and Experimental Study.

The activation of potassium fluoride for nucleophilic fluorination of alkyl halides is an important challenge because of the high lattice energy of this salt and its low solubility in many polar aprotic solvents. Crown ethers have been used for increasing the solubilization of KF during several decades. Nevertheless, these macrocycles are not enough to produce a high reaction rate.

Remediation of a Riparian Site in the Brazilian Atlantic Forest Reached by Contaminated Tailings from the Collapsed Fundão Dam with Native Woody Species.

The failure of the Fundão dam in Brazil spilled alkaline contaminated sediments (pH ~8) into the Doce River basin. The contaminated sediments had high levels of ether amine (6 mg/kg) and Na (54 mg/kg) in relation to those in preserved sites. In the present study, a riparian forest was established over contaminated sediment using 2 main remediation strategies: phytoremediation with species native to the Atlantic forest and previously selected for their tolerance to sediment toxicity, and physicochemical remediation by incorporating organic matter (OM) into the sediment.

Prevalence of Blastocystis sp. infection in several hosts in Brazil: a systematic review and meta-analysis.

Background: Blastocystis sp. affects a wide variety of animals and is the most common protozoan in human fecal samples with potential pandemic distribution. In the present study, a systematic review and meta-analysis were conducted to determine the prevalence and distribution of Blastocystis sp.
