Immune Responses to Respiratory Syncytial Virus Vaccines: Advances and Challenges.

Respiratory Syncytial Virus (RSV) is a leading cause of acute respiratory infections, particularly in children and the elderly. This virus primarily infects ciliated epithelial cells and activates alveolar macrophages and dendritic cells, triggering an innate antiviral response that releases pro-inflammatory cytokines. However, immunity generated by infection is limited, often leading to reinfection throughout life.

Gender-Related Trends in Publication Authorship: A 10-Year Analysis of a Brazilian Surgical Journal.

There is a gender gap in the representation of women in the authorship of surgical literature worldwide. In Brazil, data on the gender distribution of the authorship of articles are scarce; and hence, there is a lack of awareness about the contemporary situation of women surgeons within the academic surgery in the country. In light of this, we conducted this study with an aim to describe and evaluate the authorship trends in a Brazilian surgical journal over a period of 10 years (2010-2019).

Women representation in academic and leadership positions in surgery in Brazil.

We aimed to analyze the representativeness of women surgeons in academic and leadership positions in Brazil. We investigated women representativeness across surgical departments of 25 Brazilian universities (2020); across boards of 10 Brazilian surgical societies (2020), and, as speakers, in 281 surgical events (Jan-2014 to Dec-2020). From 383 individuals in university departments, 43 (11.

Sedation versus protective stabilization for dental treatment of children with caries and challenging behavior at the dentist (CHOOSE): a study protocol for a non-randomized clinical trial.

Background: There is a lack of evidence on the effectiveness of moderate sedation in pediatric dentistry, compared to protective stabilization, which remains routinely used in Brazil despite moral questions. This prospective non-randomized clinical trial's objective is to evaluate the effectiveness of moderate sedation, compared to the protective stabilization, in the dental care of children with dental behavior management problems.

Methods: Participants will be 152 children under seven years of age with early childhood caries (ECC) who need specialized dental treatment due to a history of challenging behavior during dental care.

Periodontal Changes After Caries Management in Preschool and School-Age Children.

To evaluate the effect of caries management on the periodontal status of preschool and school-age children.
Twenty-six four- to eight-year-old children with at least one primary molar with a deep carious lesion were selected to undergo a periodontal evaluation before and six months after dental treatment. Two examiners conducted the periodontal exams using the visible plaque index (VPI) and gingival bleeding index (GBI).

Impact of non-restorative cavity control on proximal carious lesions of anterior primary teeth on the tooth survival and patient-centered outcomes (CEPECO 2): study protocol for a non-inferiority randomized clinical trial.

Background: Studies have questioned the necessity of restoring cavitated carious lesion on primary teeth, once the control of biofilm is the most important factor to arrest these lesions. This randomized clinical trial aimed to compare the survival of teeth treated with a non-restorative cavity control (NRCC) compared to resin composite restorations (RCR) on proximal carious lesion in anterior primary teeth, as well as the impact of these treatments on patient-centered outcomes.

Methods: A randomized clinical trial with two parallels arms (1:1) will be conducted.
