Breastfeeding and a suitable eating plan in the first years of life are crucial for the development of premature children. Early exposure to ultra-processed foods (UPF) can lead to an increased risk of chronic diseases. To analyze premature infants for breastfeeding practices, intake of ultra-processed foods, their health risks and other associated factors. Data on diet and sociodemographic variables were investigated using questionnaires. We used anthropometric assessment according to WHO growth curves and laboratory tests to analyze the lipid profile. From the whole sample, 51% never received exclusive breastfeeding, or received it for less than a single month; 29% received between four and six months; in 84% another food was introduced before six months. After the stratification of consumption between “none/one type” and “more than one type” of UPF, the variables “child's age” and “family history of overweight/obesity” were positively associated. After bivariate and multivariate analyzes, a greater diversity of UPF intake was associated with family income 2 minimum wages and employed mothers. Premature infants are at risk of early weaning and use of AUP before even six months of corrected age.

Introduction: ketamine is a dissociative anesthetic and, recently, its antidepressant properties has been described. Besides, its safety has been proven in the treatment of Stimulant Use Disorders. Objective: to evaluate the use of ketamine in the treatment of Stimulant Use Disorders (specially cocaine and its byproducts). Methods: patient's motivation for change was measured by URICA scale and psychiatric symptoms by EAS-40 score, both before and after the intervention. Results: it was verified, after the comparison between the Readiness Score means, an increase in the motivation for change after ketamine’s single administration, when compared to the moments before and after the intervention. Analyzing the Global Severity Index before and after ketamine administration, by EAS-40 score, we noticed a slight reduction of the psychiatric symptoms before and after the intervention. Conclusion: it was proven that ketamine's single administration led to a quick and lasting improvement on the user's motivation without worsening the mental health status.
