Sedentary behavior, physical activity and body composition in adults.
We investigated the associations between objectively assessed sedentary behavior (SB) and moderate-to-vigorous physical activity (MVPA) and body composition variables among a representative sample of Brazilian adults. ⋯ Our findings on the unequal association of physical activity with body composition variables between sexes can help inform future intervention strategies in Brasil.

Acute pulmonary embolism (APE) is an important cause of cardiovascular mortality, due mainly to hemodynamic instability. In these cases, the recommendation is to perform some reperfusion procedure, with systemic thrombolysis being the main therapy used. However, national data evaluating the efficacy and safety of thrombolysis are scarce. ⋯ Thrombolysis in patients with high-risk APE or intermediate-high risk had a severe bleeding rate of 17.6%. However, the high mortality of this population (47%) due to right ventricular failure justifies the use of this therapeutic modality.

Analysis of the chemerin and resistin adipokines in children and adolescents.
To compare the serum concentrations of adipokines resistin and chemerin in children and adolescents with eutrophic and overweight and to evaluate their relationship with anthropometric, biochemical, and blood pressure variables. ⋯ the adipokines analyzed presented a distinct profile in the groups of children and adolescents with eutrophic and overweight.

Challenges on participation in a cooperative group of childhood renal tumors in Brasil.
Children with renal tumors included in clinical trials have significantly better outcomes. In Brasil, the enrollment of patients in clinical trials remains challenging. Here we aimed to describe participation accrual in the Brazilian Wilms Tumor Study Group (BWTSG) and to identify barriers to trial registration of children with renal tumors. ⋯ Our results demonstrated low accrual of participation in a cooperative group trial in Brasil. We identified variations in registration rates according to geographic region and hospital, which may help targeted efforts to increase registration rates. The survey responses demonstrated that colleagues understand the importance of trial participation.
