A risk score for predicting death in COVID-19 in-hospital infection: A Brazilian single-center study.

Background: There is a paucity of information about Brazilian COVID-19 in-hospital mortality probability of death combining risk factors.

Objective: We aimed to correlate COVID-19 Brazilian in-hospital patients' mortality to demographic aspects, biomarkers, tomographic, echocardiographic findings, and clinical events.

Methods: A prospective study, single tertiary center in Brazil, consecutive patients hospitalized with COVID-19.

Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS): a Brazilian cohort.

Background: Paediatric inflammatory multisystem syndrome (PIMS) associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been described since mid-April 2020 with the first reports coming from Europe. Our objective was to describe the characteristics of patients among the Brazilian population.

Methods: A multicenter retrospective study was conducted with the participation of five pediatric rheumatology centers in Brazil during the period from March to November 2020.

Selenium nutritional status and its association with SLEDAI-2K, HOMA-IR and lipid profile in Juvenile Systemic Lupus Erythematosus patients.

Objectives: To assess nutritional status regarding selenium in adolescents with Juvenile Systemic Lupus Erythematosus (jSLE) and analyze possible associations with disease activity, insulin resistance and lipid profile.

Methods: This was an observational, cross-sectional study of 31 female adolescents with jSLE and 31 healthy female volunteers as a comparison group. We obtained demographic, anthropometric (weight, stature, waist, and neck circumferences), and clinical data (disease activity measured by SLEDAI-2K) from both groups; laboratory data including: lipid profile, plasma selenium, erythrocyte glutathione peroxidase activity (GPx), plasma malondialdehyde (MDA), ultrasensitive C-reactive protein (usCRP), insulin levels, and glycemia (Homeostasis Model Assessment for Insulin Resistance-HOMA-IR).

Monitoring self-reported adherence to antiretroviral therapy in public HIV care facilities in Brazil: A national cross-sectional study.

Introduction: Patient adherence to antiretroviral therapy (ART) is critical for HIV treatment success. Monitoring rates of adherence in public HIV outpatient care facilities can improve outcomes in Brazil where ART is universally available.

Methods: We conducted a national cross-sectional survey of ART adherence in 2010.

Prognostic model for patients with traumatic brain injuries and abnormal computed tomography scans.

Traumatic brain injury (TBI) is an important cause of death and disability worldwide. The prognosis evaluation is a challenge when many variables are involved. The authors aimed to develop prognostic model for assessment of survival chances after TBI based on admission characteristics, including extracranial injuries, which would allow application of the model before in-hospital therapeutic interventions.

Thromboelastometry versus standard coagulation tests versus restrictive protocol to guide blood transfusion prior to central venous catheterization in cirrhosis: study protocol for a randomized controlled trial.

Background: Liver failure patients have traditionally been empirically transfused prior to invasive procedures. Blood transfusion is associated with immunologic and nonimmunologic reactions, increased risk of adverse outcomes and high costs. Scientific evidence supporting empirical transfusion is lacking, and the best approach for blood transfusion prior to invasive procedures in cirrhotic patients has not been established so far.

Factors associated with injuries in adolescents, from the National Adolescent School-based Health Survey (PeNSE 2012).

Objective: To estimate the prevalence of injuries among teenagers and to examine the associated risk factors, such as sociodemographic characteristics, risk behaviors, family ties and other factors.

Method: The prevalence of the outcome (injury) was estimated with a 95%confidence interval. In order to verify factors associated with the injury, a bivariate analysis was made with estimated odds ratio (OR) and its respective confidence intervals.

Situations of violence experienced by students in the state capitals and the Federal District: results from the National Adolescent School-based Health Survey (PeNSE 2012).

Objective: To describe violent events experienced by school-aged adolescents in school, around the school and in the family context, and to compare the results of the National Adolescent School-based Health Survey of 2009 and 2012.

Methods: Indicators related to violence involving teenagers were analyzed. The prevalence rates and confidence intervals of 95% were calculated for events of interest according to gender and type of school (public or private) and regions.

Bullying and associated factors among Brazilian adolescents: analysis of the National Adolescent School-based Health Survey (PeNSE 2012).

Objective: To estimate the prevalence of bullying from the victim's perspective in Brazilian school children and to analyze its association with individual and family context variables.

Methods: An analysis of the data on 109,104 adolescents, obtained by the National Adolescent School-based Health Survey, held in schools in 2012, was carried out. An association model between bullying and explanatory variables was tested in different contexts: sociodemographic, risk behaviors, mental health and family context.

Psychoactive substance use, family context and mental health among Brazilian adolescents, National Adolescent School-based Health Survey (PeNSE 2012).

Objective: To evaluate the association between the consumption of psychoactive substances (tobacco, alcohol and illicit drugs) and demographic variables, mental health and family context among school-aged children.

Methods: The National Adolescent School-based Health Survey was held with a national sample of 109,104 students. Data regarding demographic variables, family background and mental health were collected.

Lifetime use of illicit drugs and associated factors among Brazilian schoolchildren, National Adolescent School-based Health Survey (PeNSE 2012).

Objective: This study aimed at describing the prevalence of illicit drug use among 9th grade students in the morning period of public and private schools in Brazil, and assessing associated factors.

Method: The Brazilian survey PeNSE (National Adolescent School-based Health Survey) 2012 evaluated a representative sample of 9th grade students in the morning period, in Brazil and its five regions. The use of illicit drugs at least once in life was assessed for the most commonly used drugs, such as marijuana, cocaine, crack, solvent-based glue, general ether-based inhalants, ecstasy and oxy.

Focused cardiac ultrasound: a training course for pediatric intensivists and emergency physicians.

Background: Focused echocardiographic examinations performed by intensivists and emergency room physicians can be a valuable tool for diagnosing and managing the hemodynamic status of critically ill children. The aim of this study was to evaluate the learning curve achieved using a theoretical and practical training program designed to enable pediatric intensivists and emergency physicians to conduct targeted echocardiograms.

Methods: Theoretical and practical training sessions were conducted with 16 pediatric intensivist/emergency room physicians.

[Hyperhomocysteinemia in children and adolescents with systemic lupus erythematosus: evolutive evaluation].

Introduction: One of the mechanisms implicated in the pathogenesis of coronary heart disease in patients with juvenile systemic lupus erythematosus (SLE) is the hyperhomocysteinemia. Our aim was to follow patients with juvenile SLE and to identify the presence and the persistence of hyperhomocysteinemia.

Methods: We studied 18 patients with juvenile SLE (median age 13.
