Malocclusion, bullying and oral health-related quality of life: are they associated?

This study investigated the presence of malocclusion and bullying and the effect of these factors in oral health-related quality of life (OHRQoL) of Brazilian adolescents. As result, bullying and previous orthodontic treatment had a statistically significant association with OHRQoL, demonstrating the psychosocial importance of orthodontic treatment. Read More →

Parenteral nutrition administered by familial caregivers at home: Is it possible?

This study aimed to present the experience of training familial caregivers how to use parenteral nutrition at home for children and adolescents participating in a multi-professional intestinal rehabilitation program at a university hospital. The project concluded that such a practice is feasible in the public health system in Brazil. Read More →

What it if rains? Research advances in weather forecasting during launching missions of the Brazilian Space Program

Study characterizes the precipitation events that can occur during the dry quarter in the region of the Alcantara Launch Center. Data collected over 37 years was used to confirm their average features and obtain the large-scale organization of the convective activity during higher precipitation events. The results presented could be helpful for short-term weather forecasting during launching missions. Read More →

Can Dachshund dogs develop retrobulbar meningioma?

A study of a female Dachshund breed with altered neurological signs resulted in a diagnosis of multifocal lesion. At necropsy, it was found to be a rare tumor in the retrobulbar region, affecting only 3% of dogs. The research draws attention to the importance of including this possibility of pathology during diagnosis. Read More →
