Objective: Evaluate the influence of photobiomodulation in a model of oral carcinogenesis induced by 4-nitroquinoline-n-oxide (4-NQO).

Subjective: Ninety-six Swiss mice received topical application of 1% 4-NQO on tongue dorsum, for 20 weeks. The tongue was subjected to photobiomodulation with red (71.

Background: Traumatic dental injuries (TDIs) in early childhood exert a negative impact on the quality of life of children and their families. However, there is no evidence from cohort studies on which to base prevention strategies at the beginning of life, when children are entirely dependent upon supervision. The aim of the present study was to estimate the incidence of TDI in the first year of life and explore risk factors in a birth cohort followed up in three major cities in different regions of Brazil.

Effective decontamination of hospital surfaces is crucial to protect workers from antineoplastic drugs (ADs) since dermal absorption is the main exposure route to these hazardous medicinal products. Sampling after daily cleaning in oncologic settings from a tertiary hospital was initially performed and exhibited low contamination levels; however, cyclophosphamide was still found (up to 957 pg/cm) above the guidance value (100 pg/cm) in four locations, evidencing the need to properly assess and update the cleaning protocols. Then, cleaning efficiencies of six solutions and different protocols were evaluated (including, for the first time, four commercial cleaning solutions/disinfectants not designed specifically for AD removal) after deliberate contamination of three model surfaces with 13 pharmaceuticals: bicalutamide, capecitabine, cyclophosphamide, cyproterone, doxorubicin, etoposide, flutamide, ifosfamide, imatinib, megestrol, mycophenolate mofetil, paclitaxel, and prednisone.

Background: Nonenveloped viruses, such as hepatitis A virus (HAV) and parvovirus B19 (B19V), are not inactivated by detergents and solvents commonly used to manufacture plasma derivatives. Cases of transfusion-transmitted HAV and B19V have already been described in several countries. This study aimed to determine the incidence of HAV and B19V asymptomatic infections in blood donors from Rio de Janeiro and evaluate the residual risk of transmission to blood derivative recipients.

Frailty is a concept that is emerging as an important tool in the preoperative assessment of patients. The incidence of frailty in vascular surgery patients is high and is expected to increase concomitantly with the aging of the population. The identification of these patients and their optimization in the perioperative period can lead to an improvement in their outcomes with a reduction in morbidity and mortality.
