Combined single-photon emission computed tomography-myocardial perfusion imaging with coronary calcium score for assessing coronary disease.

Purpose: Coronary artery disease (CAD) underestimation represents a major pitfall of single-photon emission computed tomography-myocardial perfusion imaging (SPECT-MPI). Coronary artery calcium score (CACS) has emerged as a sensitive tool for the assessment of suspect CAD; however, the integration of SPECT-MPI with CACS has been seldom evaluated, so far, and was therefore the aim of the present study.

Methods: Patients undergoing SPECT-MPI with CACS and subsequent coronary angiography were included.

Student's perception of school bullying and its impact on academic performance: A longitudinal look.

Introduction: Bullying among peers has immediate and long-term consequences, as it affects children's health-related quality of life. The aim was to examine the association between the frequency, type and dynamics of children's involvement in bullying situations and their academic performance over the school year.

Methods: Longitudinal study conducted in 2015 in 9 to 12 year-olds in schools of Bahía Blanca, Argentina.

Bullying at school: Agreement between caregivers' and children's perception.

Introduction: Bullying at school is usually kept secret from adults, making them unaware of the situation.

Objective: To describe caregivers' and children's perception and assess their agreement in terms of bullying situations.

Methods: Cross-sectional study in children aged 8-12 years old attending public schools and their caregivers.
